I keep seeing conflicting results on putting a BOV on my MK1 Audi TT 1.8l turbo. Some say it will make the fuel run rich when decelerating and maybe if stall the car. But others have said it cause no issues.
I put one on my car this morning and took t for a drive but I haven't seen any ill affects.
I do hear more turbo spool when accelerating after installing but that's isn't a bad thing as I like that sound.
Any one have any hands on experience putting a BOV on the same engine?
Cheers

 

From the FAQ

Bovs are ok to use on the car, but not all cars will accept them with stock power. To use them, you MUST have a valve that is closed at idle. These include a twin piston valve and a HKS ssqv. This prevents thecar from stalling and leaking air at idle. It will also not run rich after the car adapts (sometimes not needed to at most 2 days). The best bovs are the forge004 and ssqv. For BT applications, a tial 50mm bov.
