Intakes make great power. They drive fine too when you have a tune. I recommend TurboTrix very highly for expertise AND customer service.

Put the stock back on, it feels much more punchier than the AEM intake...

Kind of concerned with the fact that my Guage still only goes to 10 or 12psi though...

What exactly could be going on here? I'm totally lost.

Interesting.

Take your car to the dealer & have them check out the stock boost solenoid. Mine failed @ ~3500 miles.

I experienced similar low boost levels. Maybe the diaphram is torn in your w/g throttle actuator?

Think I solved my problem, just spoke with a guy here "Laakness" .

He had a similair problem to mine.... he had the same guage as me....

Mine hovers @ 10 VAC when the car is off, and goes to 20 VAC when the car is on... I thought it was odd that it wasn't at 0 when the car is off but whatever.

I have a faulty guage.

Try getting the gauge that tops out at 30PSI. Oh yeah, my gauge goes directly to zero when the car is off.
