Hi i have a 1994 wrx with full exhaust(decat) induction kit and dump valve. The car came fitted with a HKS boost controller but i cannot get it to boost over the standard boost, I can turn up the boost on the controller but the higher the boost level goes the less time it boosts for, its kinda difficult to describe but it justs runs out of steam!
Any one else have this problem any suggestions to over come this? Cheers
