Nice comments always give some motivation...

Today I finally got to convert the cooling fan so it works automatically. Seems to work fine. Bleeded coolant system. Adjusted the spring in MAF so it's tighter now and now engine works even at low rpm's beatifully. Did a little test on the driveway again, now in second gear, pulled quite nicely even without much boost. Seems like I read the boost gauge wrong first time cause now there was much less boost. Needs some adjusting.

Made a decision, gonna order TurboSmart Boost Tee, wideband AFR sensor/meter and FMI 4.3 RPM limiter. I wan't the limiter so I can adjust it so it cuts ignition just before it would hit the factory fuel cut limiter. Don't wanna let it lean out.
