, been wanting to try this for awhile so i thought i would try on a tune that i used to move my truck out of the garage,, have a look tell me what needs to change, the truck is 1985 Scottsdale short box 2wd, 2 1/2 dual exhaust all the way to the rear bumper with thrush oval mufflers. the engine is 2001 4.8 with no maf i'm pretty sure it's a dud. Stock cam,intake,no rear O2's,, not even sure it's a 4.8L pcm, i think it came from a 5.3L truck
In the backyard spin file i got it warmed up and took it up to 4000 rpm in park i think , don't remember , then i spun the back wheels to get load data
