Rob777.. do you have any clamps or zip ties on the tube that goes from the intake to the boost solenoid, don't try using a screw on hose clamp i tried one on mine and it snapped the brass nipple off the intake side,
I'm not sure which way the airflow travels through that tube, is it more a vacum or does it build boost in it.. anyone? Corksport don't supply any clamps for that hose in their intake kit.
I had to put the stock intake back on and used the corksport tube it still stuttered, i put zip ties on each end and the stutter is all but gone. I know yours isn't stuttering but it may be making a whistle if it aint clamped
