Hello everybody!I have a 04.5 lly efi live tuned by me 4inch staight pipe banks inter-cooler and intake with scoop ppe egr block off and shim kit with ppe liftpump suncoast 3 with ats 5star and copilot gt4088r.I just wanted to tell you a little bit about me. So I'm wondering how far I can take my stock rods? I have the truck tuned for 2100 rpm and up anything less and its stock.I'm a little scared to tune anything less than 60mm3.Does anybody have any thoughts.Thanks
