Hey peeps, FNG here.... Anyone got any suggestions for tuning after installing a comp cams 54-455-11 cam in my 06 GMC sierra 4.8L? I havent put the cam in yet, but i was wondering if i can properly tune it using my diablo tuner or if i'd hafta take it to someone to get it right the first time? Daily driver so i cant afford downtime, only vehicle i have! Currently getting ready to drop in some 4.10s in the rear, then the cam will be next
