Anyway, I'm having some sort of fuel starvation issue. I'm now running at a constant 9psi...which is really ODD! And my A/F went from 11.2 to 12.2 and the numbers are constant on the Dyno. Not sure if my Kenne Bell Boost-A-Pump is acting up or something screwed up in my fuel map. But its causing me great annoyance and pain that NO ONE can seem to figure this out.

Any help here would be great!
There is a TSB out for problems with fuel pumps on the S197s.

And with that much boost, I highly recommend the GT500 Fuel pump kit. You are more than likely runnning out of fuel pump.
