I've been watching this for a while, and I couldn't help but wonder if any of the other vendors out there are developing a tuner for the 2011. I kind of want to pull the trigger on a H&S Performance, but I wanted to wait a while and see what else came available (besides BullyDog).

Some post say others are in the works but have not been able to get it working right yet. The only one that will not do the 2011 is EFILive.

Jbarker has said later this year for Banks... I have heard late this summer for Edge. PPE says they are working on it... But who knows that is all just hear say. I think were just gonna have to be patient.

When did EFIlive say no? I had not heard that.

I purchased a H&S yesterday. I'll put my word in on what I think about it.

Did you go with the mini max or the black max? I rode in a lml the other day that was strait piped(basically just the stock exhaust hollowed out) with a mini max and i wasnt too impressed with the power :confused:

I ordered the Mini Maxx... I sure hope it has some more power...

What tune was it on? They do include a stock power, mild, wild and Hot tunes.

I hope somebody has something good to show video wise for the chipped LML. So far only one impressing is the 0-95mph video and it almost looks fake cause it climbs so fast.
I wanna get a new truck but am not ready to step out of a mid 12s LBZ and into a maybe mid to high 13 if lucky LML.. Looking to hear more feedback from fellow LML owners with chips....

i asked a couple of times if they are going to do a tune with 300 hp increse but noone responds. a good friend of mine has a 09 ford with a 315 hp sparten tune. this thing is a rocket. i would like to try and take him out:)

HP tuning numbers are limited by the capabilities of the hardware installed on the truck. The LML will never make a 300HP gain on stock parts without some serious giggle gas or other steroid. 500HP is looking to be about all the LML will push on stock parts.

From what i have read with my Tranny done on my LBZ and PPE Hot +2ET i should be around 520+ range..
So from what your saying the LML can make 500hp with just tuning? That should be pretty close in 1/4 mi times to mine...? Especially with some tranny tuning ..? I just havent seen proof that they are comparable to what i have . I want to see some cause i want a new truck. : (

It was on the hot tune the whole time! Maybe I'm just crazy and expecting it to be faster than my truck. It pulled well but not like I thought it would

I don't have any reason to believe that 0-95mph vid is faked, but I didn't make it so I can't say for certain. If you count it out though it looks like ~6 seconds 0-60 which seems right for ~500rwhp but a 2wd non-boost launch.

You can absolutely tell that the TCM is forcing some big-time defuel on the shifts. That will hurt 1/4mi times absolutely, but hopefully keep the trans together until MikeL comes out with some good parts for us - and hopefully the TCM tuning to take advantage of those parts.

Thanks for the direct feedback H&S! I don't think anybody should be upset that an entirely mechanically stock motor will do 500rwhp/1000rwtq! I'm curious if/when you'll be testing your Hot tune at the strip or longer pulls? Will the stock fuel system maintain rail pressure (and those HP/TQ numbers) for a full 1/4mi pass? What is the weak link beyond the current limits (i.e. where would the first place for a mechanical upgrade to the LML, besides the trans, be)? Turbo, injectors, intercooler, fuel - all of the above?

Your built tranny is very likely the reason your truck "feels" faster than what a LML with the H&S tune on Hot might feel like. Until we get some trans parts available for the new Ally behind the LML and figure out how to tune the TCM I think it'll always "feel" a little soft on the shifts (and the 0-60 and 1/4mi will reflect that).

It was on the hot tune the whole time! Maybe I'm just crazy and expecting it to be faster than my truck. It pulled well but not like I thought it would

Strange. As above I guess it's probably the trans that is disappointing you, but it's so hard to say without any numbers. I'd tell your buddy to get it on a dyno and see what it actually puts down and get it to the drag strip. I don't think we've seen on tuned LML put down a 1/4mi yet. As I asked above I'm really curious if the fuel will keep up for a full 1/4mi pull, if EGTs will stay reasonable for a 1/4mi, and with the shift defuel what they'll actually run. As soon as I get back from AFG I'll be doing that myself but I wouldn't mind seeing what some of y'all are doing as well.

Ok, I lied...

I got a chance ( and sunny skies) and put it on this evening. I put it on the wild setting (DPF Present) and it is definitely an improvement. The throttle mapping isn't so bad now, a lot more fun to drive.

Ive only done a few hard kicks and it will break the tires looks for split second until trac control kicks on. A lot of gray smoke out of the tailpipe when you do a WOT kick.

I must say it shifts just like a dream so far and I haven't even done the trans learn yet. I know more about how I like it in the next few days.

Wow good to hear... I am surprised you were impressed by the shifting, this is good news. Lol at the gray smoke you better get that DPF off there before you plug it up:hehe:When you putting the exhaust on??

You had EFI on your old truck right?

So is this truck a dissapointment (or leave you wishing you had more power) after coming from what you had ??
That's what scares me from buying a new one!? : (

Power wise yes, but that's not fair to compare a big tune truck to a stock one. The H&S is nice, Ive got it on the hottest setting of the DPF present tunes and it still isn't nothing compared to my last truck with a 425RWHP tune IMO.

Well i guess i need to hear more from people with DPF DELETED trucks and how they compare ... I was hoping with the 500 HP tune that they might be really close to mine..

Nobody has put one on the track yet and that is the only real way to tell. Your truck has a lot more then just a tuner on it, it is also a good bit lighter

After a long drive tonight..Dead pedal is still there. I really wish H&S would try to remap that throttle. When it hits 2-> 3 shift the truck flies otherwise.

Looks like Ben is correct.

If you are still running DPF Present, that is why. With aggressive fueling before the Mass charge flow can support it, the NOX and Particulate count increases exponentially. This would clog the DPF and you would see excessive regenerations and likely other problems. It is really nothing to do with the throttle, but with the way the fueling is commanded and limited. With the race tuning, I would bet you feel a lot better about the "dead pedal".

Who is Ben? What is he correct about?

So does anyone have means to run these trucks with DPF delete and race tunes at the track? I need to decide whether or not to trade my 06 in or not... HS, can you guys go run one at the track ??

Did EFI Live ever say they were definitely not planning on LML support? Everything I've read said that Cummins support 03-11 would be completed before they looked into it again, but I dont think they completely wrote it off.

They wrote it off... They said if GM kept the ECM unreadable from the OBD2 port they would not support the truck.

Im pretty sure the ecm is readable...

so what does this mean if no efi live for the 2011 are we not going to see any high hp trucks? or are companies like H&S going to offer a tune to make say 800 hp? or are people going to be reverting back to stacking again?

Im pretty sure the ecm is readable...

How do you know that? It's pretty well known around the WORLD this ECM can't be read from the OBD2 port. Yes, you can crack it open and pull the file from the chip but EFILive will not proceed with that route.

Calm down tough guy, I dont believe I ever said you were lying. After looking into it further, it looks like the ability to read the tune is no longer available with this ECM. This is quite disappointing for EFI Live users, but might open up the possibility for stand alone controllers.

As soon as the hard parts start being released we will know more. I will bet that H&S will be providing a tune to match any mods, mild to wild. Right now we are up against a few hardware limitations before the horsepower can go much higher.

One of you limitations are; your big tune does not come anywhere near 508 hp. Bring your test truck here and let Westech dyno it. :cool:

I do know that the 80hp tune makes 380 to the wheel on my dynojet. So I can't see your 150 HP tune making 500?

Do you by chance have a dyno run that same day, same dyno, same calibration factors, with the stock tune? A dyno is a tuning tool. I can make a dyno read any peak value I desire. What is important is the net GAIN between two runs, not the final HP number.

I would still like to see an H&S tuned LML run some 1/4 mi times.......!!!??? OR run against a comparablly tuned older Dmax..

should be interesting

I raced an 2006 duramax with ppe hot tune 300 he had fuel shims and lowered all the way he ran a 13.8. He only beat me by one truck lengh

Lowered and a lighter truck that isn't to bad

And a bigger tune!""

^^ what are you running in your truck?

Just h&s tuned 150 hp. Runs great!!! Smokes a lot to

ppe also measures hp gain at the crank (I believe) so he was maybe running a 225 whp tune and h&s measures at the wheels so he maybe has 40-60 more hp than you and lighter so ya makes a difference.

Yeah but they are both pretty much max effort tunes for the stock turbo/fuel system. Both PPE and H&S claim to put out around 500rwhp which is about all your gonna get out of them. That is if the Dyno numbers are actually true

I didnt do a stock run. But I can do it. I can make my dyno read higher numbers to but what good is that. This was done on a dynojet on Sae smoothing set on 5. I will eventually have the 150 tune in there and will do the stock the 80 and then the 150 tune all in the same day. I will post when I do.

Great, let us know the results. We have found that 5th gear is the best, with the speed limiter turned off. Load that dyno up and let the truck work for it.

Thanks.

Same here, truck made 314 stock, 379-380 sae on wild. This was also on a dynojet, it sucks that the tranny downshifts even in manual mode. You have to time the throttle just right to keep it from downshifting.

I have seen some stock numbers in the 350 range posted here, but not sure if they all used load dyno's.

A loading dyno is for sure the best way to dyno on these trucks. You probably would have seen 350 or so stock (ours averages 340-370 stock), and significantly higher tuned numbers.

So how does the H&S tune the ECM, but efi can't? Is it that the ECM won't open the stock tune to change it, you just have to send the tune in I guess you would say?

In so many words, yes. We read all LML calibrations here, so there is no need for the end user to read their ECM.

is the shift on the fly going to be available for the lml? gotta a couple guys asking

Only EFI Live can answer that. I am unsure of what they can and can't accomplish. I have heard they will NOT tune on the LML as long as the end user cannot read their own ECU.

Man, I was really looking forward to getting at least an economic tune on my new LML to help with mpg's a little bit. Does the H&S help with diesel absorption? :D

Goto the EFILive forum site and read through the post they have under the LML and why they will not be able to tune LML ECMs. Like mentioned they have to read the tune out of the ECM in order to the changes one will wish to do. Something about the new Bosch ECm does not allow reading of it or portions of the memory but one can write to it with no problem. Yes one can get any calibration tune off the GM website but one is not allowed to make changes to it and a bunch of other things. All Copyright law issues on that portion.
