[QUOTE="4cstr, post: 146937, member: 516"] What setting are you running in on your chip? Does the truck feel like its making power...or does it feel like a slug? I agree with BigAl on looking for boost leaks. Do you have a set of gauges? If so...are you making any boost or are EGT's running warmer than what would be considered normal for driving lightly daily. And even though it not make a big difference...clean or replace that airfilter. [/QUOTE]
