[spawn87]

Do you still have your stock BOV? That is the problem if you do, they can't hold pressure to save their little plastic life. Good luck, Keith.

a quick cheap fix is the 1g BOV, can withhold way more boost especially if you do the crush mod

It could be a number of things. First thing that I will ask is if you have any way of monitoring the knock of the car. If not, turn the boost back down. If you do, is it knocking? Turning up the boost, and not adding fuel, will cause the car to knock at some point, and when it does, the car will pull timing, making the car feel sluggish. Another thing to check while you're troubleshooting, is do a boost leak test. Make sure everything is up to par on the car before you start trying to make it go faster.

ok so i put my psi back to stock 11-12psi...but im still gettin that power loss feel. it happends around 5000 rpms ... i was wondering what did you mean by getting something to monitor the knock?...im trying to get a greddy type rs bov but i dont think thats the problem.

You still on the T-25? There ya go.

but the power lost didn't feel like that before. i know the little t-25 i have is weak but i still havent decided what turbo i'm going to upgrade with. um doing the bolt on mods fires. next is 3' turbo back...but back to the subject is that a normal feel then?
