So I put in my Dejon Tool MBC yesterday. After 1 momentary spike to about 11 psi, everything appears to be adjusted and functioning properly. The difference between 4psi and 7.5 psi is deffinately noticable. It feels like it spools once, then spools again. Kinda neat...I'm deffinately addicted.

By the way, if anyone is looking for a simple boost controller, this one seems to be great for the price ( $89.95 from www.dejontool.com ). So far it's very responsive, no spikes (that is after I got the damn thing set).

badass! did you get the dual one with the electronic solenoid? I really want to know where they got that solenoid or who makes it. I am going to make my own dual mbc and hook up the solenoid to my cruse control switch on the steering wheel. Then at the track i can juts run 3 psi and hit the lever to go up to 10 once i get traction. Ill probably to a write up, that cruse control thing on the wheel is perfect. Ill probably use a relay to keep cruse control working..

Yeah, i already built one of those. It works great! But i want to adjust my wastegate actuator to like 3 psi, then set it to 10 psi or so with the MBC and have an electronic solinoid to bypass the MBC. So when i dont give the solinoid 12v it will bypass the mbc and the wastegate will open at ~3 psi, then i hit the switch and the MBC will alter the signal giving me 10 psi of boost. I think this will keep me from spinning my wheels thought 2nd gear at the track!
