I have the juice and attitude and plan on upgrading to the hot juice when it is here. I also have plans on an SCIII soon. I want to stack, been looking at the Predator, but have heard several different stories on this paticular one.
I like the features of the Predator(diagnostics, data, speed limiter, etc.). I'm looking for a good gain for somewhere around the same price.
TTS sounds awesome, but not willing to pay that kinda money and have to worry about changing ECM's, waiting for custom tune, yada yada. I want something easy, reliable and worth paying for to stack with the edge.
Can anyone help? Is the Predator really that bad? Power pup? HOw much does the VA box run for, can't seem to find much info on it.
Thanks ahead.

Predator seems pretty good to me so far. Decent power, not a lot of noise. It also corrects for tire size and removes your speed limiter. Being able to read/clear codes is also nice. I say go for it. The price is descent and it is a nice addition to any power adder collection. :ro)

I've only driven it for a day now so more to come.

Better call Predator first to make sure they tried it on a 2005.

I'm going to test a few LLY tuners on Saturday at the dragstrip. I'll post results. The LLY Predator took me to 14.42 from a 16.6 same day with no other changes.

http://www.diablosport.com/U7185.php is says on the site.. 2004.5-2005 also I am running one on my 05. seems to work fine

Predator has been very good on my truck so far....the 100hp program makes plenty of smoke in my opinion:rolleyes: Nice to have the features to change the tire size, speed limiter, etc. I've been running the 65 hp program now that the snow has started to fly...All in all I would rate it a very good product....

anyone have times on the j/a stacked with the predator. I know it's early, just curious.

does the predator show up on the computer when you take it in for some warrenty work? also the same for the power pup? is stacking those 2 chips a bad idea for a stock tranny?

how yall like the new sig? I LIKES!!!! maybe I need a lil more to back that up though, heh?

With the Predator (or any flash tuner) what happens if:

#1) Before it stores your back-up stock settings for the first time something goes wrong in the data transfer. Does your PCM program remain untouched until the re-write process?

2) What if during the re-program process the predator fails (data transfer) and your PCM is only partially programmed? Will the truck still run?

3) How about if you lose (or someone) steals your tuner. How do you get your stock program back? Tech II?? Cost??

4) Say you have a mechanical problem. Truck won't run / Electrical problem and you take it in for warranty work. There would be no way to re-flash the PCM back to stock before going to the dealer- right??

Thanks for the education!

#1) Yes
#2) No
#3) Tech2/TIS2000, 50-100 Bucks, plus towing
#4) Maybe, if there were a major electrical problem

Thanks! Just Trying to make an informed decision.

Here's the truth about PCM tuning. There is a risk, a small risk, but a risk. If you want to experiment safely, you are best off having 2 PCM's.

If the PCM dies so you can't communicate with it, the dealer can replace it. Don't expect them to foot the bill though.

you cant stack those 2 as they both program into the pcm, you could stack the predator with the bully dog harness device though

Don't expect them to foot the bill though.Exactly Pat.....Every now and then the dealerships have a problem with losing communication with a vehicle during a reprogram...from what I understand that locks the pcm and the only cure is a new pcm....Nice thing about that is if the dealer is doing it, and they lock the pcm, they replace the pcm at no cost to you......

hmmm, i guess it could mess up the pcm - thats why a reprogrammed pcm is a great solution or a pcm on stand by. ive had a downloader lose communication while trying to program but i was able to back out and start over and not damage anything

So, if I understand you correctly the "safest" (if you will) tuners would be one like the Juice that only modifies the PCM signal rather than re-flashing the PCM. Once the tuner is disonnected the PCM remains intact. Correct??

Rob

Correct !!

05LLY2500HD,

The thread is yours again - sorry :)

The safest solution is not to modify your truck.

But the harness boxes are safer on the PCM than repetitive uploading.

Once your PCM is tuned, the failure rate is no worse than a stock unit. But constantly changing the tune increases the chance that something may go wrong.

I tuned my Corvette about 50 times. One time the engine would not start, but disconnecting the battery for 10 minutes, pulling PCM fuses and leaving the ignition on allowed it to reprogrammed again.

The risk is small, and it's the actual uploading that causes the risk. Running a "custom tune" is no more risky to the PCM than running the stock PCM.

Understand that you can control more of the engine functions using a PCM tune. You can effectively change the "logic" of how the truck functions. At least in theory, the most powerful tunes are available by rewriting the PCM.

I would stay away from the Predator. Also stacking that on top of the Juice is going to be hard on the engine. Get a Duramaximizer, this stacks really well with the Juice, i have one, cause it adjusts fuel rail pressure and will stack about 50hp on top of the Juice without causing issues. If you really want a programmer go for the xcelerator by Pacific Peformance, they are top notch, they make the Duramaximizer.

Is the Duramaxizer out for the LLY?

I've never been a big fan of Predator's gasoline products, I hate to say it, but it works pretty good on the LLY. IMO, better than the LLY Edge.

My ONLY complaint about the predator for now is that it is a little bit noisy (raspy) upon light acceleration when the engine is cold ~30º after it warms up a little bit it is as quiet as ever. Also if you get into the throttle a bit more it goes away.

I definately like not having to wait for the engine to warm up for it to add power. It should keep the alli shift nicely all the time.

I have only tested the 100hp stacked with juice on level 0 so your results may vary.

For me, the Duramaximizer is far too much trouble to install and uninstall for warranty work visits. Check out the install instructions HERE (http://www.duramaximizer.com/install_guide.htm)

Question - If you have a flash tuner like the Predator and you have downloaded your stock tune program into the Predator and have your PCM reflashed at the dealer, DO you re-download your new stock tune (after the new re-flash) into the Predator as an updated "stock Tune"? And if you didn't, wouldn't it be possible to go back to your old stock tune by downloading it from the Predator if the new dealer "re-flash" was causing problems?

Rob

I was wondering the exact same thing..

skory - some thoughts on what you posted, whatever is programmed on the pcm prior to the reflash will be lost - done deal - IIRC. So then you have a programmer that thinks it has a loaded tune in the vehicle but doesnt, im not sure what would happen at that point as the parameters it thinks are installed are not ?? generaly you would want to return the vehicle to stock, get the reflash if thats what you need, then reprogram and you should be good to go. You would have to know someone who could completely reflash your pcm if you wanted to get rid of the reflash IIRC

What got me to thinking and asking the question was this thread (http://dieselplace.com/forum/showthread.php?t=16212) :confused:

the only way i know of is to have someone with the ability to completely reflash your pcm, i.e. not the dealer. there may be some people on here that can, not sure if they would or not, but i do know that it can be done

I was on the Diabl Predator web site and read that the D-amx Predator tuner can be used to run diagnostics on any GM ODBII vehicle. I didn't know this. This would be another plus for me because I could use it for diagnostics on the wife's '01 Yukon. Has anyone ever tried this??

I read some codes on my friends 02 Envoy to see what had set his SES light. Anyhow it will read certain data on gas engines, however it will not read nearly as much as it does on the diesels.

So yes it will, but only to a limited extent.
