In need of some help.....

[DOQ fastlane]

Over the past few days I've noticed when I come to a stop the rpms drop unusually low and almost stalled a few times.
I just installed the awe Turbo outlet pipe and now when I come to a stop it stalls out when it hits 1k rpm.. Every time
I took everything apart.. Checked it all and it seems tight, and don't hear or feel any leaks

I called my mechanic (at home.. Great guy) and he mentions possible vacuum leak.
He also says to try to disconnect the maf sensor and drive it again to see what happens..
Crazy enough, it stops stalling.
My mechanic said first thought may be the maf is going bad.. But nothing solid.

I just wanted to hear your thoughts on this before I move forward on having it diagnosed..

Thanks

Do you have an aftermarket air filter? (the type that can be washed and re-oiled)?

Does your car build boost at all?
If it doesn't check your TB

You might want to check your MAP sensor as well, its on the TB pipe.

Check that you didn't roll the seal where the outlet pipe connects to the intercooler.

Sorry I didn't update this... But Pat.. That is exactly what it was.

Reinstalled and it's running like a raped ape.
Boosting spikes at 22psi..holds at 19psi
