im slowly adding perforance parts to my truck and the latest upgrade is an edge evo. the truck detonates a little on extreme but is all good on tow, so now that my dumbass figured that out im staying on tow. but my question is should i put a wideband on it and play with the tunes a little? or just run it on tow and leave it alone?

i would tune old school style and read plugs but with the 5.4 spark plug issues im scared to do that
