My car is an A4 with 3.73 series 2 gears in the rear. I have the stock rims on there 245/50/R16.

What is the best method for recalibrating the speedo? I've had PCMforless calibrate it when they did the rest of the PCm tuning for my car, however, I'm off by quite a bit - 140 MPH on the speedo, 107 trap speed at the track.

What other info is needed in order to help this along? Thanks

I would send it back to Bryan so he can double check everything. I'm sure it's a mistake. If it was indeed programmed for 3.73s, it would have been correct.

 

This has been a problem for a while now, I think I had him program the PCM in 2003, late in the year. I sent it back to him last year, early in the year and now I've been dealing with it. My only concern is that it's too late to have him re-program it again and I kinda don't want to pay for it if I do have him do it again. Sounds kinda ****ty but if it is a faulty program, ya know.

Plus I may just wait and do it all over again when I get my new cam setup installed.
