Is there a good stock tune on efi live or one of the other tuners? maybe a notch above stock , I don't have emission test as of right now ,I live in Va. so with the weight no emissions but I don't need a race truck, just good power and fuel mileage and don't have alot of money to burn on this project, but looking to get longevity out of it,I read that most take egr and pfe off is that needed or can something else be done as a workaround. Once again its a 2009 ltz trim pkg,Lmm,6spd with 50,000 miles on it untouched, oil changes every 3k and conditioner every tankful so any helpful tips to keep this baby running.
