330 performance cams?..

There is no 15whp gains for ZHP cams, not over standard 330i cams. Even B25/B28 cars probably wouldn't see that much gains.

There was on my car.

If he had no tuning before cams then put headers on his car, and cams.... I can believe a 15 whp gain total after tuning.

Hoveringguy gained a net 2whp on those cams.
Anyhow, I'd love to see your dynos, cams or no cams.

Blueprinted motor + milled head + port work + intake + Headers + custom tune + stock 330 cams -> all that but + ZHP cams =~ 10-15hp from 5k-7k. I need to dig up my dynos. They're buried on my old IBM laptop.

Fair enough, did the tune get updated
for the cams as well?

Yeah, fresh tune.
