Sorry but I don't buy it!
What works is LT's, Cold air intake like Vararam, Haltech, Rotofab, CAI in that order. Also the vmax TB's for better response and a good Ecm and TRANNY tune. Period. That's just bolt on stuff excluding cams n other stuff.
No tornados, POWER wedges or AirRaid spacers or granatelli MAFS or JET 50hp plug in modules DO NOTHING!
