Guinea pig = 2004.5 LLY DA 4x4 Sierra 3500 SRW, ~7300lb raceweight. 200lb weight reduction, tailgate and spare removed.
Mods = No Cat, Suncoast III, TTS Triple T/C. Otherwise stock down to the ashtray.
Place = Famoso Raceway, near Bakersfield California.

For HP, look just at MPH, not ET. For stoplight warfare look at ET. All devices set to Kill, no trans backdown, no temp backdown, max settings. Units were tested by launching powerbraked to generate max RPM (boost) before launch.

Predator LLY 100HP - 14.49 @ 92.05
Bully Dog LLY 120HP - 15.12 @ 89.34
TTS LLY 50HP - 15.42 @ 86.7
Edge Attitude LLY 120HP - 15.85 @ 89.66

Stacking
Predator 100 + Edge 120 - 14.76 @ 90.82
Predator 100 + Edge "3" - 14.78 @ 91.90

Stacked testing stopped at that point, as it wasn't going anywhere. See Notes.

Notes:

Predator 100 - The hardest launching tune, was also the best behaved during shifting, as well as the fastest. Threw a P1093 code on the way home, which puts your motor in limp mode, limiting the RPM to 2000. Predator can reset with it's DTC reset function. Boost "realtime" info reads 0 psi all the time. It will stall all the way to 2900rpm which was more than my truck could handle. The front end jumped left to right and back again erratically. Launching at 2500 proved to be quicker and less abusive to the front end.

Bullydog Power Pup - First thing is SCARY. It freaked out during upload scrambling the screen and locking up. May have been a factory defect. After turning everything off, and restarting, it recovered. Couldn't build full RPM powerbraking. 2.26 60' times were the best I could do. Felt pretty good though. MPH indicates the unit puts out the same HP as the Edge.

TTS 50HP Tow Tune - This is a custom PCM tune. To test, I brought 2 PCM's to the track, one TTS, and another stock for the Bully Dog and Predator. Smooth, predicable, but not intended to be a drag tune. It was the second quickest 60' time. It seems only 2 of the devices fully remove the LLY "1st Gear Defuel" that plagues the LLY, the TTS and the Predator.

Edge LLY w/Attitude - It certainly makes power, so why does it run so slow? Even set to Kill, I could not get it to launch hard. I powerbraked it FLOORED for 10 seconds but it never made full boost. 1500RPM was the best I could do. Once rolling, it appears to defuel the shifts even when told not to. For power, it's good, but for drag racing? Needs some help. The poor first gear performance carries over to stacking. I have stacked it previously with the TTS, and saw the same thing, so I did not bother trying to stack it with the Bully Dog. It also exhibited the infamous Turbo Bark trait, and is the 2nd production release unit I tested.

Thanks go out to John@DPS, MrMagu, Mike L, and Trippin for help with the testing.

Sidenote - My truck runs SLIGHTLY quicker in Normal than Tow/Haul mode. All results posted in Normal. And Trippin's truck stomped my poor LLY into the dirt.

 

Great info,I am close to picking out something for a buddys LLY,was leaning towards a hypertech,only because it needs to be easy for this guy to deal with once loaded in,hes one that wont even look under a hood,the kind of guy that really should leave it stock. Also price is good on the hypertech.Thanks for all the info you posted.Please advise welcome

 

The best "stock" tune that I've tried is the TTS Tow Tune. You can tow full weight, uphill, in the summer with no issues. Acts like just like stock, except 2 seconds quicker in 1/4mi. Totally "rookie-proof". Dyno'd at 65rwhp.

Haven't tried the Hypertech LLY. Couldn't get one in time.

The Predator on 100HP will probably limp the transmission. It acts like a 140RWHP tune. But DAMN... 3 seconds quicker than stock. It has 5 settings, with 100 being the hottest.

 

I ran a 14.7 at 90 w/ a 1.9 60' with full exhaust (no cat), intake and the Edge w/ Attitude on a LLY. All of this with a tool box, 2 people in the truck, and it was with a Crew Cab Reg. Bed. Plus it was defueling on shifts bad.

 

My buddy talked to a guy that claimed to have tried most all,his opinion was banks ,this was on a non LLY,any opinions? banks wants $ for everything.

 

I personally like the Edge products, they have 5 levels of power that can be switched on the fly, they have a really sweet display screen, easy intallation and alot of safety precautions built into them. And like I said I ran a 14.7 with one, which is good, I know with a built tranny I could see low 14's, maybe high 13's with really good weather.

 

i love edge products. odd that it didnt make the mph like the predator. on our LB7 (old school duramax lol) we made 405 rwhp and around 800 rwtq. i am NOT a fan of hypertech, even if it is cheaper.

 

I wish I could have gotten the Edge LLY to launch. My MPH seems to agree with yours, but my ET sucked because it left the line in Grandma Mode.

Not sure why. Some people are reporting wild differences between LLY Boxes.

I did run a 14.88 with a "Second Beta" Edge stacked on a TTS Tow tune the month before it was released to the public. This was a late production release version.

I love the features and power of the Edge. I just wish I could one to run right on my California truck. I've tested 4 different Edge systems.

But for now, the Predator is significantly quicker than anything out for LLY to my knowledge. And I hate Predator.

 

I wish that Edge had something similar to the TTS Extreme that could be switched to on the fly. I like the 5 levels but sometimes it would be nice to have more but with the option of running a tow tune without changing boxes.

BTW, how do you like your suncoast tranny?

 

i wonder how the westers and hypertech would have faired against them...
