Hello to all,my name is josh.Just bought an 05 dmax, havent had it a week yet. from what ive read here, ppe tuner seems to be the "best" handheld imo. i wanna do a cold air intake, magnaflow exhaust,egr delete and some sort of tune. will i get a code if i do an egr delete without a tuner? can i do all mods except tuner without hurting trans? lastly if i get a ppe tuner and occasionally run it on the high setting with just doing a suncoast converter. this will be driven 3-5 times a week. towing a 2place snowmobile trailer and maybe a 36 foot enclosed race car trailer once in a while.thanks.
