I've never driven a 328 but I'm sure that with my current mods, I have more power than a 328 -- says my butt dyno

It actually gives 40+ Hp for a 325i. My car is faster then my brothers 330i. So obviously it worked.

Agreed. I drive a 2006 325i with the production date being in the first half of the year and the only problem was t-stat and water pump.
