wanting my tune looked over i believe its safeish truck has head studs and oringed. im not understanding why a pedal map makes the truck start slower/faster? i tried a few others that i found and came up with this as a happy medium but not understanding why others made the truck start faster but the drivability was crap. also cant seem to get rid of a small puff of smoke when going wot happends anywhere from 1500 rpms to 2500 rpms when you punch it i took more fuel out in them areas but still does it ( usually around 15 psi+)03 6.0 manual.hpt
