I used a mechanical gauge, and definitely have vacuum. Starting to think it's just the sensor.
as for how rich the car is, i double checked injectors, they're stock, and scaled appropriately.

Like I said, pulled the tune with ecuflash, and compared it table for table to a stock tune. Only difference was high octane ignition and fueling maps. Which don't have anything to do with idle or cruise. I might just take it to a shop, really has he stumped. Who do you guys recommend in the tristate area besides Ivey?

Check the periphery bits and thresholds for open loop.

He works some magic.

I'll check the bits tonight though, do you know which they are?

fix all boost leaks first, then if the problems persist, continue troubleshooting. You should be able to hold 25psi no problem. The massive leak you described in your valve cover makes me think faulty pcv valve, but you will have to test.

you make a valid argument lol, how does one test their pcv valve? can you literally just blow in it? I'm assuming if you blow through opposite of the valve cover side, and it opens, its bad?

Still not fixed... too freakin cold to work on it here in NJ.
I'm ordering a BOV and I'll retest for leaks around the PCV and oil cap.
Is it still believed that the stock evo 9 bov is best for boost levels under 25 psi?
