awhile back installed a Forge WGA in the X, i aslo previoulsy add installed the Perrin MBC, well with the mbc turned down all the way i was still boosting to 26 psi or higher, so finally after a few over boost and tired of not haveing a tune, i took the MBC off today, the car still hits 25-26 psi, but it doesnt spike to it and cause limp mode or any problems, i also installed the AMS intake heat/fan shied whatever you wanna call it, and it has infact done its job and help fixed the damn engine idel issue most of us have been having.

 

I have ordered the JUN actuator which allows you to set between 14-18psi.

I'm running stock boost soleniod and stock map at the moment, how many psi should I adjust on the JUN so it would be safe and no boost spike?

My guess is if you leave it at 14psi, it should hold factory boost of 21psi to redline.
Whereas if you adjust it to open at 18psi, your boost level will increase to 25psi will hold to redline?

Is the stock fuel map safe even at high boost level?

 

Interesting, I had installed the Greddy Profec 2B EBC, it was overboosting cause i had the vaccum hoses messed up. I fixed the problem

now it wont go over 10 psi.....might be an actuator problem too.
