Hey guys, lately when I hit boost in usually 3rd gear it sometimes sounds and feels like the turbo is cutting in and out. Just wondering if anyone knows what I could do to check what's wrong with out taking it to a mechanic?

I lost boost once, turns out I left it in my other pants.

But seriously check the bearings and listen for noises on shutdown. Check all the hoses and joints , maybe you have an intermittent boost leak. Try cleaning the boost solenoid.

I think it does have a stock fuel pump. It has been tuned about 4 months ago with a flash tune. I have a boost gauge and it shows it dropping from 10 to about 2 or 3 psi then back up again.

It's definitely not your coils and plugs?

Its normal for boost to drop in the mid range if you have a generic tune or a safe custom tuned. Esp if you have a mechanical gauge.

Obviously generics are far from safe though.
