I did notice, however, with one of the two mags that I put the high flow valves in that I was getting shots more in the 285-290 range... not much better than stock mags. That "bad" mag performed the same in both guns. With the "good" mag, I got 310-320 (with .25's) and with the "bad" mag it was down in the 290 range. I am going to fiddle with it more tomorrow, and try installing the high flow valve on a different mag to see if it makes a difference.
So excellent results with the Hurricane Kit in the ATP's. With the high flow valve in the mags, it is strange that one performs much better than the other... and I double checked that I had in fact installed the high flow and not accidentally re-installed the standard valve in the bad one. Has anyone else seen similar issues?
