First here's my combo: Trick Flow Street Heat, 70mm TB/Spacer,70 MA Sensor, Stock motor, 12Deg timimg, 93 Octane.

I keep getting lean codes on both banks and I can hear what sounds like a vacuum leak, especially if I listen through the air box. I've chacked everywhere for a vacuum leaks and come up with nothing. Also the car seems to be cutting out at 5K rpms. Usually it would pull to 6K no problem. Any suggestions?

did you check all of the lines behind the intake and going to the vacuum tree? Is the intake torqued all of the way? If you can hear the vacuum leak near the airbox, make sure all of your hose clamps are tight around the MAF sensor and TB.

Have you done any recent work on the car?

Find a shop local to you that has a smoke machine like us. It hooks into the main harness and pumps smoke thru. Then look where you see smoke coming out from.
Hope that helps.
