Well for a long time now I have been trying to tune my FIC for 20psi. I have never been able to get it quite right. Because of the difference in fueling from the factory computer at say 60% throttle opening at 10 psi compared to 100% throttle opening at 10psi. If tuning for 100% throttle you will be very lean at 60% throttle. If tuning for 60% you will be pig rich at 100%. I have tried to find a happy balance but its just not possible. I have turned the boost down to the 12-13psi range. This is a little bit more managable. To get the full potential of this built motor it will need a stand alone. Its just more then I want to spend at the moment.
Just curious how does the boomslang hook up to the AEM EMS and the factory computer at the same time. I now the power steering still needs to hooked to the factory computer. Also can I still use my A/C. Anyone know?
