My friend ran 15psi on his SOHC crx with a greddy IC'd kit, but the bad part is that he is using a FMU and refuses to keep the boost under 8psi...

Is there anyway of testing a FMU to see if has gone bad ? The car has a missing link, stock injectors, stock FPR, and FMU for fuel manigment, but the A/F guage is ALWAYS in the green at idle !!! It leans out up top at about 6-7-8psi.. we can't figure out any reason his car would ALWAYS set at RICH RICH at idle...

Also, how can we test the injectors ? He did run them at XXX psi when he had the car running at 15psi, for now he is running 8psi max, but he said once he gets stuff worked out he's going to turn the boost back to 15psi on the FMU !! I can't stop him...

 

15psi more power to him!
