i have a 95 gst with a 14b turbo and every thing else.. the problem is when i get to 4rpms it will start to hessitate really bad and the boost will only get to 5 psi when im just pushing 10 psi. this problem started when my o2 scensor cords got cut and zapet my ecu and fryed it so the car was running really rich for awail.so i put in a new o2 and new ecu and i start to notice a lil knock and i check my knock sensor cord and it was broken so i reconnected the wires. i also put in new plugs and wires
