Doesn't work with N55. HPFP does if you have the "E85" connector attached.

Is the _THR pedal response more similar to stock? It seems like the standard BEF (9E60B_E85) made it lazier at the same JB4 settings.

I'm also curious about the difference between _E85 and E85_PI....

I guess that's another thing to try if it comes back. Did it cause any of the other symptoms above like malfunction and poor running?

I don't agree with that. The stock turbo, among other things, is intentionally stunted because people were having too much fun with N54s and making M3s look silly. If I were given an N55 car and...
