I got nothing from my Shaner ported truck TB. It was advertised as bolt-on power, but when it didn't gain he then asked why I didn't re-tune the car for the throttle body. So, which is it?

i have a magazine article hot rod or car craft. where they built up a 1999, started stock engine dyno gained 32 hp from fast 78mm intake, TB 78mm, and maf 85mm. they said over 20 hp was intake. so TB & MAF gained 10-12. i will dyno mine next spring with only TB change. if you want article i'll find it for you .
