I think I’ve solved the vibration. I inadvertently pulled apart my stock drive shaft when reinstalling the transmission. I took it apart today and found where there is a mark on the transmission side of the shaft and 2 lines on the U joint on the diff side of the shaft. Lined those up and now my ride is much smoother!

I finally got a little exhaust sound clip. My car is awfully dirty…have to take her to the car wash tomorrow.

My last issue is to get the AC belt to stop squeaking…

More tuning and dyno yet to come. Once I master the 3.5” pulley tune, then off to the 3”. Then i'll have to update my sig!
