Thanks for everybodys help. Lately my 86 951 has started to do a very annoying thing. Once in a while while I'm rolling on the throttle in the mid range of the rpm band the car will start to accelerate and then BAM it feels like it has hit a wall. I have watched the boost gage and it wasn't even at an indicated 1.4 bar. It usually happens when I am cruising at about 40 and roll on the throttle. This morning while getting on the freeway I had reved out first then second and while I was at 5K in third and an indicated 1.6 bar it hit the wall again. I was at wide open throttle this time.
I recently installed a boost enhancer but it is turned down so low that I can blow it open with just my lung power, just a few psi.

Any help would be greatly appreciated.

Thanks, Threesticks
