Need Details!!

[wrhorer]

My truck is a 08 GMC 2500HD with the 6.0 gas with 33x12.5x20 tires.... 6 speed auto trans. I havn't purchased a programmer/tuner for my truck but will this week. Every programmer I've researched says that the 6 speed tranny can't be tuned in my truck and limits other perimeters. I am looking at the Trinity now but i havn't seen any details on approx. HP gains, economy, towing, or if my 6 speed(shift points) can be tuned wth this program. I like the format of the Trinity but I'm very undecided and confused on wich programmer/tuner is best for my truck. My truck is spongy on takeoff and needs more power for pulling.....i usually pull a 30' 5th wheel and 30' aluminum horse trailer. Any help will be appreciated!!!

I was also looking at the inTune.........

Trinity should be able to tune your tranny. Its the 6L80, right? The Trinity tunes my 6L90 fine.
You should get about 15-20hp throughout the rev range.

There really are no other tuners. DiabloSport offers the only tuners that allow custom tuning to suit your mods, and to dial in your specific vehicle. None of the other handhelds allow that. To many people, thats reason enough to buy from DS.

Not sure if its the 6L80 or not.........I have the vin# if it wld help...the 8th digit is "K"(seems like that matters on these trucks)....its a 6 speed auto. I jst want to make sure im getting the right programmer that i can utilize to its full potential for that amount of money. I dont want to be dissappointed....lol!!

your truck uses the new E78 PCM, not yet supported...

[wrhorer]

ok not to sound like a dumda$$........but explain "new E78 PCM"....I'm new to all this lingo.....does this mean not supported by any programmer? not right now by the trinity but will be? if so how long?...... not being a smarta$$ , just really curious...lol

[mikel]

correct, as I understand it, nobody has anything for the new E78 as far as tuning goes...yet

[wrhorer]

why does my 2008 GMC 2500HD 6.0 have a "new E78"????? Everywhere else I look the E78 is in 2010-2012 year models.......

sorry, my bad, i missed 08, and thought 2011-12 for some reason.
