Re: help please boost problem
I was having a problem like this, But my car has a boost cut at 15psi & it was cutting at about 10psi. Ended up having a hole in the line going to the boost gauge and boost was actually higher then it was reading. So I replaced the line and turned down the boost. Now it runs fine.

1. Check for boost leaks.
2. Make sure TPS is calibrated and working correctly.
3. Switch back to oem MAP sensor, and have a tune that reflects this change.
