i finished my setup, d16z6 and boosted at 7psi. Im usin an fmu and it seems to me like its not kickin in. When i hit boost my a/f gauge grops to lean and the car doesnty go. When i hit boost on the highway my cel came on and started to idle like ****. turned car off and drove under boost and cel light is gone. My fmu was laying around for a month after use is this my problem? is my fmu gone?

get a fuel pressure gauge and mount it on your windshield. watch the fuel pressure as you boost.. the fuel pressure should rise to like 60 psi from about 30. if it drops pressure as your boosting then your not getting enough fuel pressure from your pump... check for any leaks, none? you then would first change your fuel filter, if that doesn't do it, you need a fuel pump.

good luck!
