Well...beee carefull becuz ur going to have boost creep and you might be boosting like 10 psi. To be safe about it, i would port the wastegate on the turbo, buy fcd, fuel pump, boost gauge, and manual boost controller. Thats the best way to go ! Porting the wastegate on the turbo will lower your boost into way safer levels, say like 6 psi or 5!

A boost controller can only RAISE boost - no help for you.

Porting the waste gate is the most important.
I am still running the stock waste gate on my S5 & boost creep is a problem.
