I have a 1986 928s with the 32V engine. A few months ago I installed a Autothority Chip set. It was a great improvement. My question is: Has anyone used this chip in combination with the x-pipe from 928 specialists or 928 motorsports on a 85 or 86 model?. I am wondering how these parts work together. will I need to do any other tuning? Any dyno results?

I am leaning towards the 928 specialist kit with the removable cats. I live in Kentucky and no emission check is required. This kit is $649. the comparable kit from 928 motorsports is $983. If i get the kit with no cats from 928 motorsports with no cats in mild steel, it is cheaper.

928 motorsports claims 27 hp. 928 specialists claims 24 hp.


I probably would have already installed a RMB, but my car is the early 86 model so it is not offered.
