At it's peak, the most fuel I was throwing at that poor little 351 was as follows:
5x.014 injectors, 024 DV's, Air Dog 150, 2095 Rack plug, no fuel plate, AFC modified, 4K GSK. When I had the HX35 on and switched to the HE351, all the fueling mods were the same except no rack plug and stock DV's. I could bury the pyrometer past 1600* with both turbos, so not exactly sure what the difference in EGT was but the 351 took a little longer to peg out the gauge. You gotta do something about the drive pressure though, I don't know if rules will let you run an external wastegate but I highly recommend it. I was pushing max boost of 42psi and max drive pressure of 60psi with the 50mm wastegate.
