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)
