I went to get my 2004 Cobra dyno tuned on the new setup yesterday and need opinions. I just switched from factory pumps and BAP w/wiring upgrade to twin GT pumps and modified FPDM to give myself a little head room and according to the datalogs I'm maxxing out my fuel pump duty cycle. Peak boost was 18.5# and at 5200rpm my duty cycle was 0.4994. I thought I should be 75-80% duty cycle with that setup...am I crazy? We also noticed that my voltage dropped to 12.5-12.8 volts during the pull so would that have anything to do with it? If so, any help or suggestions would be greatly appreciated. Thanks!
