sell the bov and just get a simple bosh bpv........thats wat i have, its loud, sounds epic, and it works amazing. the only thing u have to do is stretch the hoses over the bosh ends because its bigger then normal hoses. and there also cheap. idk if that's the Bosch 110 or the 102 in the pic but the Bosch 110 has a stiffer spring, which is good because the 102 has been known to leak due to a weak spring, but i know a guy who is boosting 19psi on his mk3 with a Bosch 110 and works great. Just a thought i guess, good luck anyways!

By the way I check the codes and theres only code 51.I will see for boost leaks today.Thanks in advance

Does blow-off must be on a right pressure to give best results?
