Ok, car is stock as far as electronics. Was doing fine but after I took it to a rally-x I noticed afterwards my boost was only reaching 9-10psi. Disconected the wastegate and I get 15-20psi, so turbo is fine and no leaks. What could cause this besides the ECU itself or the boost controller? The ECU is constantly reset cuz I have a battery cut switch, so the idea of resetting the ECU is takin care of, any other suggestions?

 

Your ECU is just re-learning how you drive your car. GIve it a couple days to switch to a more aggressive map. Have you given any thought to a UTEC or some other sort of engine management? My UTEC keeps me at 15.5 psi seady all day, all the time.
