Dustin,


YOu definitely have something wrong. How in the heck are you hitting 35 psi.

1. Check the pretension on the wastegate arm. Loosen the 2 12mm bolts and check the tension, it should be snug but not to tight.

2. Run a hose from the wastegate nipple and t it into the BOV and intake manifold conneciton.


3. Did you eliminate the stock Boost Solenoid?

By using a MBC. I don't think there is anyway you could hit 35psi w/ that turbo. You may want to find another boost gauge to use.

Did cross up the boost lines during the install? Does it have the high boost actuator? With that, you can't go below 24-25psi or so, but it doesn't cause 35+.
i know of and road in an evo9 mr with a 20g-5 that was boostin 35psi on the stock motor(arp headstuds/280exhaust cam) but tuned on 100oct. with the ecutek. frickin car hauled @ss! it was maximumboost old evo9. blew out a syncro and screwed the tranny with that triplecarbon clutch he had in it car was nice though. looked bone stock except for the forge bov under the hood.

35 psi wont blow your motor on one pull . i boosted my stock motor/ turbo to that 3 times trying to set my boost controller . the only thing that it messed up is it stretched the spring in the wastegate so it only hold 12 psi without the controller

you should not have to control boost with a mbc it should run on a stock setting

All the MBC does is send air to WGA when pressure is enough to push it's spring (set by turning knob - tighter - more boost). The WGA will then move and less exhaust will spin turbo. It's like a balancing act to maintain steady psi

The aftermarket MBC system is primative, but somewhat reliable at maintaining desired psi. The OEM setup is superior but only provides OEM performance (taper)

If boost is uncontrolled the WGA likely isnt getting air, is damaged, way out of adjustment, or linkaged is bound
