I can appreciate the need for proof. Hense why I haven't bought any intakes or tunes.

With Disa there are 325/8 dynos that show 10hp gain and tq gain.
For 128i, there are no such dynos. Nor do I have baseline stats for Tourge software. I do have a dyno(128i + no secondary cat 3" exhaust) as a base.

I plan to do a dyno again, just need to know when the next cheap day is.

As far as my tune path, I dont aim for a number, just going after parts that enhance in way that should have been from factory. ( m3 suspension bits, 135i brakes and 130i power levels)

In-progress: //M front arm, M3 rack, e36M lip Wishlist: Coils, n55 mnts, headers, LSD, e60 finn diff
