I just installed a boost controller, it was kinda tricky to figure out since it never came with instructions. But when I gave the knob a few (3-4) turns and hammered it to see a difference, I felt a misfire around 4k rpm..I turned the controller all the way off and this continued. After turning my car off and scratching my nuts, I tried again with the controller off. No misfire but seeing a huge increase in boost..something is wrong. Tune? Controller installed wrong? Idk..you tell me!
