I Installed the Hypertech programer , If you want this program for better milage forget it. You will see a hp and torque gain. I used the regular gas program. These guys that are getting 19&20mpg highway, what truck did they say they had.
I recently Added poweraid spacer,S&B air intake, magnaflow catback and a Hypertech Max program for regular gas with all that Im getting 13.8 at 60mph highway. Im pissed, just give me the advertised milage. Fat chance. Please help any suggestions?
I just added a custom magnaflow catback last week and now Im hearing that tapping sound you get from an early eshaust leak. I just bought the car in late Nov . If you change exhuast is it under warenty
