Default Re: DUB Air

I've had superchips on my old Avalanche so I know how it works and your right it didn't seem to do much except change the shift point and all that you mentioned. So your saying exhaust is the next logical step? Intake , exhaust and programmer, in that order? I don't think I want to mess with headers seems like a lot of work...But with those 3 mods I should see some performance, Right?
