I'am having problems with my Blitz EBC, JWT530BB turbos are new, with the EBC off, the Turbos boosting sky high, with the EBC on they boost strong and firm, but not higher than 9.5PSI (boost is constant) in all gears. Vacuum diagram following (twin turbo modified) 2009/Nick stadsport. EGR DELETE/AIV DELETE/PRVR DELETE/CARBON CANISTER DELETE. All new vacuum lines. Currently set at 17PSI, only boosting 9.5PSI. Won't go up even when i raise gain by 50%. It feels like the EBC sets the limit there. Doesn't look like a vacuum leak? Well actually i'am a little lost here.
