Hi all, I'm very new to tuning and have been doing a lot of reading. I have only been as far as adjusting shift times an points in my wife's 6.2 Silverado.
My question is, I have a 2013 Malibu with a 2.0 turbo LTG and was wondering how do I know if it's a 2 or 3 bar map? I assume it's 2, but figured I should ask the guys that would know.
