did you get your truck dyno'd yet? like to see how rich it is, and where int he rpm range it leans out. bet it leans out towards the top end... just my guess though. like about 4500-6300. if it does, call up someone to get the fuel mapping switched up a little to fatten it up top, and trim it a touch down stairs. not much though, prolly like 2-3% of a difference. but thats just a guess. i do know you dont wanna go to far from the norn too on these trucks. then you will end up running all sorts of electronics and shit, just to make the beast run...not good in my book. keep it simple, and run the shit out of it..lol :biggthump
btw, can you get a pic of how your computer is mounted to your truck (if its in the stock location). i think my inner fenders are aftermarket non oem ones. cause i have no provisione to mount mine on. i did have mine on the firewall at one point, been so lond since i had it on the inner fender, i forget where it needs to be. thanks
