IPD Plenum, where's the horsepower
I had the plenum installed last week. I just noticed on page 63 of the May issue of Excellence magazine RSS has an ad that claims "dyno proven bolt on power" will increase horsepower by 35 HP!
I already have the Cargraphic exhaust that was supposed to give me a 20 HP boost, so now I should have 535 HP right? WRONG!
Something doesn't add up here. The plenum by itself would be hard pressed to add 1 HP. I suppose, if I were to reflash the ECU, I might see those kind of numbers on a dyno, but I would question the value of such modifications for a street application.
Buyer beware!
