Yep! Virginia Beach here. Got a question for you guys... I just put on a blitz intake and my car seems to be running with less power. I have a blitz turbo timer as well with built in boost gage; mitsubishi says a factory evo 9 like mine is boosting 20.9 psi. However, my gage only says between 11-12 psi-WHATS UP??
One more I will be adding a turbo back 3'' exhaust and a boost controller in the next few weeks. So here is my question with an intake, new blow off valve, boost controler, turbo back 3'' exhaust and a ecu flash, how many psi can i push my factort turbo?????

After being at buschur on oct 13th for the dyno day I'm convinced that the bushcur exhaust is the only way to go. You've gotta think about other things than whp though. Such as clearance 
My DP hits one of my cross members and i think its causing phantom knock. All of the cars that had the bushur exhasut had no issue's whatsoever on the dyno, and made more power than cars with similar mods and different exhausts.

We have done a ton of testing here at the shop, remember we own a dyno, and have made more power everytime we have swapped out someone else's exhaust for ours, with ONE exception. I swapped out a catback on one car that I would have bet money sucked and it made the exact same power with it off the car as it did on the car. I didn't bother putting ours on that car.

Buschur makes a good power producing catback exhaust that is extremely light for a 304 SS system. It serves many people well who arent looking for a quieter exhaust system.
