I have a Greddy Profec B Spec II EBC connected to my tial 38mm wastegate with 6psi sping, and i am having trouble with the high settings on my boost controller. i had it all set perfect for my low/high settings and then i had to disconnect my batter to work on the engine last week and ever since i cannot get it set right. the low setting works perfectly fine and i can adjust that however i want. the high setting doesnt seem to work very well though. i set everything to 0 and it still boosts well over 10psi which i do not want. before i disconnected the battery, i had a good setting of 7psi for the low and 10psi for the high and now i cannot get it back like that and io have tried everything. the low setting is fine and i currently have that set for 9 psi, but whatever i try in the high setting, it keeps going over 10psi. does anyone know what the problem is?

 

anyone?

 

bump?

 

Did you check your lines? Maybe you bumped a vac line off when reconnecting the battery? If not that...what happens if you set all the low settings on the controller to 0? does it only boost to 6 psi?

 

yeah, it will only boost to 6psi if i set all the low to 0

 

sounds like you might have a problem with the controller.. if i were you i would contact greddy. I had a similar problem at first, but my solution was found when i figured out the vac lines were hooked up wrong to the solenoid
