Ok...if anyone remebers me posting a while back that i cant get my boost controller to up the boost....that was all figured out to be a vaccum leak...well...now i have it hooked up...and regaurdless what i do, it over boosts......ever since i got it back from the dealership...theres been nothing but problems with boost...i cleaned my boost controller, flipped it around...changed some sources, nothing...im running a Hallman ES, and if its all the way open, or all the way closed, i still hit boost cut....if anyone has some ideas PLEASE give me a shout, cause its really starting to **** me off now....its been like this for 2 months now. Thanks in Advance

if all else fails use stock boost control to see if it solves your issue. if it does, then your problem lies within the boost controller. maybe you can send it back for a new one or open it up and see if the ball bearing and spring are ok. good luck.

 

i checked the boost controller, pulled it apart and all. made sure everything was back together correctly and still nothing...i mean thats the last thing i can think of, but i mean its a ball and spring boost controller.....how often do they go bad?

 

You say you've already tried hooking it up both ways? That happened with me but it was definitely due to hooking it up backwards..... You might want to check again just in case...

 

what is your boost when your hitting the cut?

 

bottom port on the controller to the "source"


side to the waste gate actuator

 

you mean you can't lower the boost even at the lowest setting?

 

The boost is not adjustable what so ever....it was hooked up either way...and nothing...ive been doin boost controllers and **** on these cars for years...but for once im finally stumped......so i honestly dont know what the hell it is

 

run the sorce line right to the waste gate should only boost to like 10 psi if not you have a problem with the waste gate

 

yup sounds like another leaker

 

did you pull the line from the stock boost control solenoid
