i just installed my profec b spec 2 and with the unit on the OFF position i heard you were supposed to boost 7psi. but im getting up to 10psi at WOT and sometimes i wont get any boost maybe like .5 psi. I was thinking maybe it is because of my modds that the boost is so high. (apexi catback and blitz intake) Also i used the NO port on boost control sylonoid to the top of turbo and COM port out to wastegate actuator. Was i supposed to plug the extra port on the boost control syloniod? (NC) by the way im running stock twins.

 

I have the spec 2 also , but my car is out of commission , should be back in a few and i will try to post after i tune and mess around with it.

 

fyi,

im runnig pfs catback,pettit downpipe, and damians intake setup im thinking of running low boost at 7 and my high set at 10 , thus i will set my warnings at 7.1 and 10.1 that i dont detonate
