95 lbs of fuel pressure is not right for a stock CIS fuel system. To be sure, have someone look up the fuel test pressure in the Porsche shop manual. I think its closer to 55 or 60 lbs (4 or 4.5 bar).

Although I agree with Goran about dynos being suspect, I think your numbers are low for what you have. When I had my CIS car, with similar mods, I used an extrude honed stock intake with good results - 410 RWHP (on two different dynos). I am still using the stock 930 heads with EFI at over 500 rwhp now. It would be interesting to hear what IA told you what you should see since there are a lot of their parts here. They should be guiding you on the tuning process too. You have a lot of stuff changed on your motor (fuel head, spark, WUR, etc), so I am not surprised its not running up to par the first day.
