Hey I have a 02 225 tt and I was wondering if bovs would be worth it cause I'm still running stock boost. All I have done so far is a new intake and a 3 inch exhaust from the turbo back. Also any good brands would be helpful.

 

here... you're gonna need this:

 

You really don't want to use a blow off valve that vents already metered air by the MAF to the atmosphere.

Your car will run rich between shifts, it's better to run a diverter valve that recirculates the air back into the intake.
