I'm now looking at using HP Tuners to modify my tunes or retune my car completely. I can get all the small details worked out myself at the drag strip. When I called IPF about updating my tunes, Andy said just to drive around with the C10 tune which is the correct fuel trims but my speedometer would be off by a lot. 3.27 to 3.91 is a huge jump.
I also looked at my old trifecta datalogs from when I was NA, my car had 12 degrees of knock retard, no wonder my car was terrible. Vince never said my knock retard was high.

So are you saying the C1D tune is the only one where the speedometer is adjusted to your gears? The C10 is best for fuel trims, but not the speedometer is not adjusted?
Shame they can't just get you a C10 for 3.91 gears if that's the case.
