Pretty hot tune, if it stays together should make decent power. Going to be a hot smokey mess for sure.

It's easy math, if 2300 microseconds equals 325 horsepower, determine the microsecond to hp ratio and then divide the on time in tune 5 by the ratio. If rail pressure is raised, 1% increase in rail is equal to about 1% increase in hp. These are general rules of thumb.
