That doesnt make sense. You should increase boost when you turn the knob clockwise which cranks the thing down. Or is that what you meant? Either way, I would say you have a bad boost leak or the valve is seized up as mine was (assuming the thing is installed correctly).

 

i also had downpipe and test pipe installed

 

i have checked on that pill and i dont have any lines going to the boost selenoid just one piece hose that goes from the top to bottom of that selenoid

 

Turn it up ALL the way and keep smashing the gas!

JJ go back to the shop and tell them you issue, and then figure it out from there.

Get nasty with them if they don't help you

 

I actually have the same prob as this fellow evo member... Does anyone know like the how much the MBC opens up as in percentage per full turn or half a turn??? ive searched a few places including evom im about to call Hallman and ask them...

Didnt realize this thread was so old sorry
