Okay I currently have my high boost set-up at 7psi. Just recently I went to try it out - Had the high boost switch on. The car only makes up to 5 psi of boost and starts to miss very very bad. Seems like it's suck on low boost and will not make more boost? Does anyone know what might be the problem??? Never had a problem with it before. Ran great up to 7psi the last time I used it. Any info would help

i assume you have a EBC? with the car off ign. on, flip your boost switch, can you hear the ebc solenoid click on? verify your electrical conn. are good.
