I can tell you now with out question your injectors are too small. 440CC injectors on a 8cylinder are already small on pump gas at 550whp the fuel pump is already compensating buy increasing pressure. You now are using a fuel that requires roughly 30 percent more to make the same power and you are now over that mark by a decent range. An easy way would be hook up a loggin software and do a log I can promise you are over 100percent duty cycle.
