I'd like to pick some guys brains. I'm looking for some advice on tuning Rail pressure to follow desired quicker when the throttle is stabbed as well as best ability to get the most out of a pump. Seems like all the tuning i do actual doesn't meet desired for a second or two and sometimes even longer but then i'll data log another tune in a truck with the same PW and rail pressure follows way faster. Any insight and knowledge behind it would be greatly appreciated!! Also if someone could explain to me the differences in what's going on with the new 10+ trucks and how the regulator is controlled as all the tuning side is completely different from that of early 6.7 and 5.9s. Thanks in advance!!!
