i need some help i bought a greddy profec B spec 2 from a buddy and the install went well and for the first week i boosted 20 lbs with out trouble and today it started stopping at 10.5 to 11 lbs no matter what i set the settings to. could some body please help

 

Help ME please

 

I have heard of this happening a lot with the Greddy boost controllers. Wastegate alone will usually run around 12psi I believe. Is it possible your solenoid quit working? I would also check for a major boost leak and make sure all your hoses are where they are supposed to be. If you cant find anything then I would hook the stock solenoid and hosing back up to see if you can build boost.

Hope this gives you some direction!

 

Definitely sounds like a boost leak to me

 

boost leak for sure

 

Check the upper IC hose and BOV seal - most common places for a boost leak.

 

Check to make sure all the vacuum/boost connections are secure. If they are, then the solenoid in your EBC has died.

 

it's not a boost leak

the wastegate actuator alone(no Boost control solenoid) will push 11-13psi....you most likely have a problem with your electronic boost controler

 

follow up? hows the car doin?

 

doin better i can get to 18.7 max now so i think a lil ride and tune is in order. if anyone has this boost controller could u give me some tuneing tips please

 

replace all hoses, to make sure its all good
