Hello Everyone,
Somewhat new to the gas tuning world (I do have some diesel tuning experience) and I have a couple questions on a friend’s truck I would like to tune. It’s a completely stock truck with roughly 42,000 miles on it. The biggest reason for tuning this truck is to eliminate the Active Fuel Management. If I’m in there to do that I thought I would try to get a little more out of the truck for him.
Question One. I have talked to a few people and most have said any time you tune one these trucks (08-15) you should disable the VATS as they can cause more headaches than what its worth. Is this true? If it is, would I also have to apply the VATS Patch as well?
Question Two. Being that the engine controller and trans controller are separate. Do I have to license the vehicle twice (2 vin licenses) for the engine and trans controller? Or once I upload either the engine or trans tune will that license both for that vehicle?
Question Three. I have tuned a 07 (Gen3) Silverado with 5.3 and with the trans tuning it was setup as normal and performance mode. I realize that is tow haul on and tow haul off. But with these newer trans controllers I see its setup into Normal, Shift Pattern A, HOT and Shift Pattern B. What do these correlate to?
Question Four. I understand I cannot make a huge difference in power with this truck, however what are some pointers I can try to get a little more out of it? My initial thoughts were to bump torque limiter (B2501). Increase torque limit per gear by 20% (B2517). Then for trans tuning increase shift times to .3000 in all gears. Then decrease the torque limiter (D1104 D2104 D3104) 10%. And increase upshift pressures in 1-4 gears 10%. Also was going to disable the brake torque management in (B2523) when traction control is turned off.
Thanks for the help and look forward to hearing from you guys!
