dont forget your bcc ,a bov on a bpu car wont do much of anything .

also make sure you have a good boost guage to monitor your boost . the ones that come with some electronic units are good but its hard to see them when there down low or too far off to your side.

i suggest you dont go over 18psi some say 19psi is ok but i dont belive so .


as for cars not sure whats around you but
some cars are stangs ,older vetts ,dsm's and so on....

BOV, you already mentioned it in your post, Blow Off Valve.
I would also recomend you to drop the idea of a BOV when going BPU.

And it may cause you to run rich and stall. I stalled a few times when I have my BOV on the auto, but never had the problem on the 6spd for some reason.

Again, it's only purpose is for the noise. (which, I'll admit, is awesome)
