Hi guys just got my car out today and when i go over 10psi of boost the car falls flat on its face and backfires and studers the only thing i did is replace my cam sensor cap the bottom piece stayed in place and no the pin is ok not broken the only other thing i can tell you is that when i adjusted my cam sensor with a volt meter i only had 5.35 volts at the max ! Is this normal and if not what can be causing this????

You may want to check your crank sensor adjustment. I thought my cam sensor was bad because of similar issues so I pulled it and it was fine. I only had like 5 +- volts also. I turned it counter clockwise until I got like .04volts with the crank at 25deg atdc. Then I adj the gap on my crank sensor and my issues went away. Good luck
