I'm running 13psi w/o any troubles. Ive been told that anything over 15 and you should upgrade to a race bypass.

I have heard 18 and over... with 15, I really think you would be fine with an inch and a half bypass.

The only thing I hated about that valve was it does leak, pretty good too. Mine stuck open once and I couldn't make more than 3 psi when it usually always made 17 psi. To fix the sticking part, I put heavy axle grease on the moving parts and that stopped the movement. Procharger sells the big race by-pass valve for $299 and it is very well worth it to buy that one.

So far my bypass is working good even though I'm not making as much boost as most of you.. Only 10lbs here but I bought the Vortech Mondo bypass valve when I bought the blower so I just have to weld it up to the intercooler pipe leading to the MAF.. It was only like $220 and flows 600cfm at 10lbs (almost as much cfm as an A-trim haha;) )
