I ran at the strip this weekend and the car was running slower than normal and just running rough. So i checked the plugs and saw a little detonation so I added 2% of fuel and put in new plugs and made a pass pulled the plugs and they looked fine. But I noticed on that pass that the fuel pressure at WOT went up to 70psi and then slowley fell down but didn't get below 40psi. I didn't think this was normal. I put on headers and with the race tune am I maxing out my fuel pump? Do I need a BAP? Or do I have a bad fuel pump? Also when I cycle the key the fuel pressure slowly falls from 41psi. I assumed this was a leaking injector because of my starting problems. Cycling the key 4 times seems to help. Help got a race this weekend and need to get this fixed?
