No offence taken. You gotta pay for your turbo rebuild somehow

I am never too busy for my customers, ask cronic about out 1-2 am tuning session on his buddy Dave's sohc z6. That thing was the loudest car I have tuned

I already replied to this guys other post, with:
A. Do a compression test.
B. Do a leakdown test.
C. Replace all the ghetto parts on your turbo setup i.e. a turbo with blown seals etc.
D. Repair anything wrong with your motor, i.e. shot ringlands, rings, seals.
C. Get your car tuned once it meets the "healthy" vehicle requirements.

A tuner can only do so much for you. If your vehicle consists of a parts in poor condition or which have been improperly installed, you will not be as happy as a guy with a healthy motor & properly installed parts etc.

Thanks,
