How's it going everyone here's my review on the Alta bov spring upgrade and torque solution bov adaptor. I order all these since i had to install both parts at once and been reading on here that any other bov like HKS ssqv or any other after market bov will throw a code. Since we use a recirculating bov from factory. There are a few YouTube videos on how to install so I won't get in to that. I followed those videos on how to install. Takes about 30 mins.

Review.
Initial drive ( I have a 07 MCS Manuel ) normal driving I felt that between shifts it has quick throttle response no lag, feels faster on butt dyno. ( no hp gain )
Under hard driving car holds boost during quick shifts tires screeching 1st to 2nd and 3rd �� ( I got 4 brand new tires also that could be the reason too ��).

All in all easy mod to install. Sounds cool like my car shushing everyone between each shift. I wish it would sound more like a HKS or greddy bov. I can't even hear the factory noise maker anymore. �� Car feels more nibble. Cheap to buy great value no cel codes����
