N80Jamie Posted May 24, 2011 Share Posted May 24, 2011 Have you got a boost controller at all? Quote Link to post Share on other sites

andy mccullough Posted May 24, 2011 Share Posted May 24, 2011 What actuator are you running, syptoms of a tired one imo.x2 or if you are using the stock one, I would recommend upgrading to an HKS one. Quote Link to post Share on other sites
lukEp Posted May 24, 2011 Share Posted May 24, 2011 Actuator will improve the boost loss but not cure it, have you still got efi pipe and restrictive exhaust? Ct are a small turbo and at higher revs struggle to provide sufficient boost the inlet on the ct9 is very small and it makes it worse when the stock efi pipe is still there.
