Default Help! Quick question on running rich...

Ok, maybe not so quick....

ok, I got the APS SR-55 and the Perrin Moded Injectors Installed. I am planing on having the STi reflashed by Shiv in the next 2 or 3 weeks because I am awaiting for other parts such as Turbo-Inlet hose, and Perrin's new Boost Solenoid.

At 1st. the car had a hard time starting but it did. However it won't drive properly, and it stalls just as expected.

I switch the 65mm APS intake with my old 70mm APS intake to help out lean the already super rich mixture. It did help but it still feels shaky, I can however drive around the block now. I am not sure how rich is running but the Autometer A/F gauge is out of its range. While driving it the CE light flashes a few times and then it goes away, a few moments later the sequence repeats itself and after a few times the CE light just remains on. This leads me to believe that the ratio is zig-zaging in the threshold between an aceptable range and the range for the CE light. All other indicators such as EGT, BOOST look good. I am staying in the vacuum side for the most part.

Question... would it be safe to drive the 400+ miles over to Shiv or I am just better off sending the ECU over to him (like someone else suggested) and let him flash a base map with the scaled injectors and then do the dynotuning at another time?

Another quickie, should I have the car tuned with the 65 or the 70mm intake? It seems pegging the stock MAF is pretty common with big turbos but I won't be runing more than 18-19 psi since I only have 91 octane to play with.
