Hello everyone I need some help with a problem. I've tried tuning my truck several different way and always have the same result. my problem is either I'm running too rich cruising and lean WOT or real lean cruise and perfect WOT. It is my daily just logged going to around my place in the middle of nowhere USA. A few 0-60ish in the log. It's a 2006 Silverado flex fule with a 226/232 lift .578, Forged rods and piston. New 5.3 bored 5.7. 243 heads ported. long tubes, flex fuel injectors which are 36#. upgraded rockers and oil pump. ARP bolts. there's more I just can't remember everything.
