Before (bone stock) at LACR:


60' 2.642
330' 7.450
1/8th 11.392
MPH 61.871
1000' 14.723
1/4mi 17.692
MPH 78.327



After (TTS Towing Tune) at Carlsbad:


60' 2.156


330' 6.306


1/8 ET 9.824


1/8 MPH 69.54


1/4 ET 15.539


1/4 MPH NA (other passes were 85.6 avg)





ARRGGHHH!!! Can't get rid of the <CR>'s


Anyways, what this means...


LACR is about 1/2 second slower than Carlsbad with non-turbo motors, and about .3 slower with turbo motors. So about 1.7 seconds quicker, or for those who don't drag, you would hit the freeway at 69mph on a 700' onramp instead of 61mph.


Biggest gains were in 1st gear. I actually jumped a Viper for about 100ft. 5th gear had little improvement.


So it was not my imagination, this tune has excellent "grunt" at low speeds, but not as much at high speed.

Hey Rat..... when's the tranny go'n in?

Hehehe... This is a "Tow Tune". As the video shows, I ain't killing any Vipers yet. This tune will allow you to kill stock SUV's and stock Ricemobiles, but not hurt the truck.

Not bad for a "dually". I have found the TTS Tow program perfect for around town commuting. For the LB7 engine, the Tow program feels substantially stronger in 5th than the stock truck (seat of the pants comparison).

Not actually a dually. It's a 3500 SRW.

Daddy lost to the viper, hell the guy in the viper was looking over at some big balls. Nice job Rat. Edited by: Wickedfn4u

Wow, those are some pretty nice gains considering it's a pretty mild tune only.


Is TTS getting closer to releasing them on the market?

That's a major increase in your 60' times.Where the runs done in 4wd with the TTS tune?http://www.dieselplace.com/forum/smileys/Big Smile.gif Edited by: speedy03

Passes were done powerbraked to stall (2000rpm) in 4WD. I found at LACR, that even with no wheelspin, 4WD launches harder.


Before the tune, 1st gear had zero balls, powerbraked or not. It didn't seem to take off until second. Now 1st gear feels just like 2,3,4. But 5th is still a bit weak.

How much better does it tow with TTS?

I was pretty surprised. I was expecting a mid-to-high 16. I had BIG 'OL grin when I picked up the slip.


Understand that between 0.5 and 0.3 seconds of the drop was due to Carlsbad being at lower altitude. But 15.5 puts me right where the Hemi's, Silverado SS's, and Titan's are running, without a loss in fuel mileage. I'm getting maybe a little better (14.9 measured vs. 14.5 before) mileage, but that's VERY hard for me to tell due to the varied conditions I drive in. I haul parts M-F for work, I do a lot of stop-n-go, but also do some extended freeway cruising.


I have no idea when it's going to be released, you'd have to contact TTS. Seems like it's ready to me. I've towed in the desert uphill in 95 deg weather, drove it for 1500 miles, dragged it, and generally beat the crap outta it with zero problems. IMO, a very good "daily driver" modification. I'm no longer sure I want a "bigger" tune anymore for normal use and towing.

You could go to jail towing 8000lb on level ground. (100mph can get you in jail). It went up the Baker Grade at 80mph with 8000lb. I didn't run into a situation where it needed more power.

This tune is for Towing and general driving. We have kept the power to safe levels for Towing in 110* heat with a full load. If we put anymore power into the tune we will lose this ability and it will begin to damage the Allison. We have enough data from the LB7/Allison combination to know what level of power things will live at for 80,000 miles. Since the Allison has very minor modifications between the two models we do not feel it's wise to raise the power any higher. We now sell this as a program only. We are working to complete our programmer at this time. We also have complete ECM's in stock for those of you that would like to have a stock ECM.

Good to hear it's working so well. I read a few of the threads about the new boxes/programers for the LLY and it seems 60hp is very safe, 90hp is weary, and 120hp and you'll kill the Allison in short order...sorta like how the LB7 motors are.


So it looks like maybe with a TransGo and a converter you could perhaps run the 90hp mode and be safe.

This is a real stupid question but from what I read there are two main types of tunes. Reprogram the PCM, and then some kind of chip replacement? If that is true going the PCM route you cant undo it to take it into the dealer where the chip you can remove?

If you order the tune with new ecm you can keep swapping the ecm when needed ( warranty issues ) - and then its pretty much the same, as you are replacing the ecm

I'm a new owner, so I'm not an expert, but here is how I understand it:


PCM Tunes: Your PCM (master brain of your truck) is like a hard disk drive on a computer. You can write to it, and it remembers. GM uploads a program to run your engine into it, controlling fuel, boost, timing, and fuel pressure among other things. This is how the TTS works; TTS writes new instructions into it to up the HP/TQ.


Harness Boxes: This is like the Edge Juice. It plugs into the wiring harnesses under the hood, intercepts the commands to the engine and changes them to make more power.


Pressure Boxes: I've never seen one, but they apparently plug in under the hood to up the pressure to the injectors.


None of these are "warranty safe". But then again, neither is any engine modification according to the mfr. You take your chances.

If you order the tune with new ecm you can keep swapping the ecm when needed ( warranty issues ) - and then its pretty much the same, as you are replacing the ecm


Correct. With the PCM Tune, you'll need to swap PCM's to return to stock. With the Edge, you need unplug and remove it. If you have the model with the pyrometer, they will see the pyrometer thermocouple, but you can always tell them that you have hooked up your gauges yet because you are waiting on parts.


In reality, if you blow up your motor by modifying it, you should foot the bill. Problem is, most MFR's will void the entire powertrain warranty even if the modification didn't cause it. Like if you have an injector leak. They SHOULD replace it because they know it's a problem with stock engines. But some dealers will refuse and leave a mark in your "permanent record" that you have mod'd the engine.


You bought a truck with 300/310HP. It was designed to deal with that power for 100,000mi. If you mod it, there is always a chance you will break something. If that is too much of a risk, you need to think about it.


Personally I bought a Turbo Diesel because it's the only engine where you up the power significantly without hurting the mileage much. I wanted a 500hp (rated) pickup that I could carry parts in, tow with, get good mileage, and carry 5 people in comfort. Nobody sells one. So I'm going to make one. Figure I'm at over 375HP (rated) right now. Dyno showed a 65rwhp gain the TTS Tow Tune.Edited by: McRat

Very well put - and exactly why i bought mine - wanted a bad ass truck that could tow my toy hauler, hold my family, looked good and had a great motor/tranny setup. Now just to add the right HP gains and im there - I have the TTS tune on order right now and cant wait to get it - i tried out the Quad box but wasnt overly impressed - but i did tow with it on the first setting and i loved how it pulled grades and such, it rips them, so i can only imagine how much better steves will be

Pretty much the same reason I bought my Max, I pull a 10,000lb 5th wheel and my family in comfort. I would like a little more umph but not at the cost of the Eng/trans. My thoughts were a turbo back exhaust getting rid of the cat. Then doing a small mod like the TTS you talk about, but to be able to do warranty I would have to keep the stock pcm right? From the web page it looks like 595.00 + 400 (if I want to keep my pcm. At that cost I would be close to the Edge/attitude price and then I get all the monitor feed back. I don't want so much power I bend my tranny around my frame.


From what I have seen the people with the LB7 have bumped up a lot of HP with out damage to the tranny but that kind of puts them where we start out so we really can't add a whole bunch more with out transmission mods. From what you stated McRat when you were pulling your race trailer it made a nice gain, this is what I want. OK and to maybe take a lightning or SS off the line would not hurt.

Here's what I do know. You will not be disappointed with the Tow Tune. There is nothing to find fault with, and I tried to. I can no longer run on the street without it, it actually makes the truck easier to drive. There are few mods that have no "downside", very rare.


I mostly post on racing forums, and have done testing on dozens of modifications. When something sucks, I will post the data and true opinions of it, even if it causes me grief. And when things are cool, the same.


If you want "kill" Lightnings, this tune will not do it. A stock Lightning will run a 14.0 typically with a 2.0 60' time. Silverado SS'es? Sure. This tune doesn't make Lightning (350rwhp) HP, nor are you as light. But you will notice a big power difference without losing any mileage.


I'm not trying to sell anyone anything, and I am not affiliated with TTS. But like many gearheads, when I find a neat tool or modification, I like to tell folk about it. Ditto with things that suck.

Is it possible to stack predator with TTS tow tune on LLY?

I called today and was surprised to find out that it would take six weeks to get one of these!!http://www.dieselplace.com/forum/smileys/Shocked.gif I figured they would enter your info, burn your chip and it's out the door. Two or three days if they are busy. I was trying to decide between the TTS and the Edge, this is another pro on the Edge side. My local supplier says he has the Edge with Attitude for the LLY in stock.........

Is it possible to stack predator with TTS tow tune on LLY?





No


Both are ECM tunes.





Mac

does that mean predator goes under the hood?


or does predator plug into port on lower left driver side?

padsave30,


What Mac was saying.........


Both of the "tunes" you speak of, the pred and TTS, tune the PCM or power controle module. The TTS is a NEW PCM with programming, while the Pred programs the PCM from the portal under the dash.


The other tunes like EDGE go under the hood. They read the signals from the PCM and change them just a little.


The Predator installs at one end, the dash. The EDGE installs between the dash and PCM, under the hood. The TTS is at the far end, the motor, replacing the computer or PCM.





This is not exactly correct but is should give you a better idea of what we're talking about. http://www.dieselplace.com/forum/smileys/Big Smile.gif

Has anyone seen the Intimidator from BD? Is it worth it? I want to at least be able to recalibrate the speedo since it is off about 17% right now and I read that it would do it. I have the edge attit. coming thursday and I am ready to have some fun. I had the edge on my LB7 and I loved it but now I have the LLY and I want to start improving it. Any ideas? Suncoast ( seems the norm) ( what is recommended, how much$?) What should I stack or what is best with the edge/***?


Reliability is important. That's why I have a diesel now. Right!


Sorry about all the questions, but with the 6 inch lift and 35 inch tires I need a lot more pep. I traded in my 2003 charcoal gray lightning with predator chip and "other goodies" for this truck. I dont want to be L fast yet, but......well that will be soon enough.


any comments welcome.


nice to meet you too!81A_MyZipFile.zip (http://dieselplace.com/forum/uploads/81A_MyZipFile.zip)Edited by: blowinsmoke

Diesel Tech,

Any problem getting a different tire size burned in with the tow tune?

You tell him the tire size you want programmed in when you order the program.

Does the Edge Juice have the ability to change tire size on the LLY's so the speedo is calibrated correctly.

No problem we do it all the time.http://www.dieselplace.com/forum/smileys/Big Smile.gif

The Edge product cannot correct the speedometer calibration, but they do offer a feature that allows speedo correction to be displayed on the Attitude display if you choose that option.
