Okay, so... I am VERY wet behind the ears with tuning but... I have done some looking and saw some do's and some don'ts. Run down of the vehicle;
2008 Trailblazer SS purchased 2 weeks ago. Mods that I knew were there - eFans (derale?), CAI (unknown name... open element). That is all that I know was done. Yesterday I installed LT Headers and ORY. Prior to this the TB was getting lean codes when pushing it, I saw multiple places that this is common with a CAI and no tuning. Pair that with my header install and that made me pull the trigger on getting this old girl dialed in. So, I will attach my file if I can figure out how to. I to this point have the MIL shut off, the COT shut off and I think that is all... looking for some direction or pointers on where to start with the MAF tuning. I've been watching GRG on YouTube trying to figure a few things out but would really appreciate some assistance from personal experience.
Thanks guys,
Kyle
