loss of boost

alexbuck205 · 04/06/2011, 09:45 PM

got my car tuned at wrenches on sat and was tuned at 12lbs

couple days later the bolts rattled out of the wastegate that holds it to the turbo so it opened up the screamer pipe.. i bolted it back up and noticed i'm only boosting 6lbs now.. checks for boost leaks and there are non.. not sure what my problem is.

bad wastegate gaskets... or check couplers, turbo to manifold can you hear or smell exhaust when idling or not in boost.

sounds like something with the wastegate check and make sure your wastegate didnt get messed up some how you never know.

i found 2 boost leaks today fixed them and took off the ebay bov and put a pit one on and still only 6lbs so idk what the hell is wrong. i have an external wastegate i just need a 12lb spring so where can i get one?

clutch sliping (this would have to be pretty extreme)?

if theres no leas, perhaps ring are fried, does it hold the 6 lbs, or reach 6 lbs and bleed down?

whats your afrs look like at wot?
oh wait, you dont have a wb.. ; )

any noticeable difference in the vac reading at idle?

EGT numbers differ from when you got tuned?
