when i added DP it went up 1 psi by utself to 7. when i added mbc i went straight to 9, and will be running 10-11 as soon as i get better intercooler.

10psi is the best mod ive done yet. I get exhaust on tomorrow, but i still think 10psi will be the best gain.

I had 10 psi, and had just turned it back down to 7 before I wrecked it. You definately notice it when you turn it up, but you really notice the difference when you turn it back down. It's night and day. You get a really good boost at 3-4000 rpm in 3rd gear. That is so worth the price of the MBC.

I've been at about 9.5psi for over a year. I love it. It's perfect for me. And; I don't have any other wildman s*** on mine. Just the boost controller, and a K&N drop in.

Like Torque222 said, Once you go up you won't come down.... 14psi all day ,and honestly its all about the way you drive.... besides with a full turbo back exhaust your car should breathe really well... I only have a catback system and its fine. The full exhaust is next on list if any.. Good Luck and Enjoy!!! MJG

7 1/2 to 10 psi

Just got done retunning my profec b. Let me tell you, I think when i go back to the track this is really going to help. Got it set for 71/2 psi for low and 10 psi for high and If i do it right i have asick launch now. I was practicing at redlights and man this is going to help because i had very liltle wheelspin and i hit the high boost at the end of 1st and that b**** was gone. It was really crazy how much this helped, if you havent tried this i would recomend it , it is kinda tricky because i dont have the remote switch and have to push it on the controller, but i got it down now.

That was 505zoom and we both think it was maybe the ecu or something because i dynoed at 9 pis and put 186 then went to 10 psi and got 201whp so who knows what was goingon them days with the ecu . I promise 10 psi is alot faster then 7psi. Ive been reajusting today to launch at 7 and then hit it at 10. I cant stand it to be at 7 psi it feels so slow now. But that is what iam goingt to try at the track to get better times .

so 9 psi = 186 whp, 10 psi = 201 whp? wow! what mods do you have?
