just fyi, if you bov currently leaks and you replace it with one tht doesnt, you may need a touch up to your tune. but looks good!

It doesn't leak. But been having a few problems lately . I was losing fuel pressure right before redline so he had to taper off boost to keep it safe. We installed a Walbro pump and a greddy bov. After this the car ran pretty bad. Thought it was just the pump running rich.

Drive 2 hrs to the tuner find out I have a huge boost Leak. He tries to scale the map for when I fix the leak. Get it back home. Fix the bov, car runs amazing. Drive it around at wot see the CEL blinking indicating knock. Check IAT they never pass 91-95 degrees even when it's unplugged... weird. Take a thermal gun to the boost pipe it reads 50-55 degrees. Think the company who sold me the speed density kit came with a bunk iat sensor. Hook up a wide band to it. I'm running as lean as 13.0 ....

So now hopefully a new sensor tomorrow and a retune Shortly to fix this. I'm also ordering an aem wide band and boost gauge. I really wanted to stay away from gauges to keep the car more stock looking but it seems I have no choice lol

The bov wasnt closing properly. There was some debris inside. We cleaned the inside and made a custom gasket. Drove it and it was a monster. Just sux, the tuner had to guess with the amount of boost I was leaking . Just way to lean
