E11v2 boost help
 

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 knob setup. Was set to run 14psi. Trim knob 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 knob 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??
