I need to DOD delete my 2011 Yukon Denali 6.2. But I would like to start in doing some tuning. I tune my own stand alone efi race car. So I think I should catch onto this.
But I also have a 2010 3/4 ton silverado 6.0L
And a 2000 of the same thing.
And a 2016 impala of my wife's, that she may or may not let me touch.
Is there a cost effective way to buy credits for this group or just for the trucks?
