Anyone dyno the actual gain of just an air intake and exhaust change?

 

BlownChevy tested the AirAid intake on his setup, I think he gained 8rwhp.

 

17 but that was with the blower.

 

A lot of magazines do dyno tests, but those guys dont know crap....also, if you do a test say stock then later that day after you install the parts, those few hp could be the difference between the dyno, the weather, ect...also, you need to consider the computers 200 mile or whatever it is "learn" time.
