The car is a 2000 GT with a GT4067 turbo, forged motor, patriot heads. It is seeing around 10lbs of boost, but will be getting 16 soon. It only does it above 5k rpm or so. On decel it smokes a little bit. Im guessing its the valve guides and the extreme vacuum from letting off the gas. Just wondering if this is normal, and what I should do about it. Im okay with the little amount if its normal for turbo cars. Thanks for any info in advance.
