Hi Guys,
New to HP tuners for sure and tuning in general with a general knowledge (Owned alot of them and can do most any maintenance/general part changing but not the level where i feel comfortable pulling motor/trans/transfer case) of GM V8's only tuning background is can tunes with the diablo. (also please move if in the wrong place but this looked like the best place to put it)
I have two vehicles i want to tune #1 already has a tune but i believe it is just for DOD disable and nothing else, #2 has a diablo i3 87 tune on it currently.
#1 vehicle is a 2013 silverado 4x4 5.3 LC9 aluminum block 6 speed
I just installed 1 3/4 stainless steel long tube headers, offroad y pipe and deleted rear cats/02s and this is the main reason im geting hptuners - would i just data log for a while and and look at certain points to tune it or is there some parameters that can be used to get it close now? I also want to do some tuning on the 6l80 right now mainly turn lock up off 1-4 , and change it to higher rpms in 5-6.
#2 is a 2009 tahoe 4x4 5.3 LMG iron block 6 speed
Stock except for the 87 tune which i am overall really happy with - the main thing i wanted to do was the same 6l80 tuning on this one - i took it to the mountains and temps got pretty hot up to nearly 220 and sometimes it shifts quirky. the can tune helped alot with the lazy stock shifts but i would like it a bit firmer and take the lock up out same way as #1 - can i download the diablo tune and tweak it?
With how bad the 6L80's are is there anything else i should do that will help extend the life?
Thanks for all your help figured with 2 vehicles this would be the cheapest route but i also dont want to FAFO and have an expensive bill because of my inexperience.
