OK, I installed my JRSC 2 weeks ago along with the JR FMU, fuel pump and set the timing to 8. Every time the car saw boost it would bog down. So i installed my air/fuel gauge and found out that it was running lean (surprise). So i just installed the JR map controller, and set the timing to 12. I went out and tested the car and it still is running lean under boost. Any suggestions on what to try next. It's driving me crazy to have a supercharger and not be able to use it. Thanks for any help.
