Hey gang,
Had my car on the dyno a couple of days ago. My S50B32 is from a '98 SMG. Since I race the car...no SMG for me. I use a manual tranny.
Anyway, while doing these dyno runs, I quickly realized that my tach is off by around 500 RPM's. I'm *assuming* that there's something going on with the fact that the package was from an SMG. Is there anything I can do to rectify the tach readings?

**I left the SMG computer plugged in since I was told the car might not run. I never tested to see, just left it hooked up.

Anyone have a suggestion?
