Hi folks,
got an erst with a few problems
Car is fitted with chipped ecu, -31 actuator, stainless exh and a K&N filter.
Car was only boosting to about 4 psi, av checked for leaks and hoses are ok.
Removed the feed for the actuator last nite and took it for a run.
Car managed to boost up to 16-17 psi before a lifted ma foot.
Anyone have an idea on what could be wrong.

thanks in advance
Roscoe
