I've done some searching on the subject with no luck. Running a e11v2 on a 20b. Car was tuned by cam at Pettit. It's using a greddy boost controller with a trim **** setup. Was set to run 14psi. Trim **** could bring it down to 7. Basically tuned with cam in Florida and everything was good, now have the car and can't get the boost above 7psi. Trim **** doesn't seem to be working. He says he changed something before the car left but doesn't remember what. Anybody know what I could check in the haltech that could be disabling the boost control??
