Just installed and I'm questioning performance. Yes...no doubt a shorter shift all around, especially 2nd to 3rd. However I have a small vibration in 3rd....is that normal? Also poped out of 3rd twice a half second after shift...is that a poor shift on my behalf or install problem? I'm an open track fan not a 1/4 miler. Nailing a shift not that critical...I just did not like stock 2nd to 3rd set up.
