first few shots low and shootdown.

[magc68]

i own a free flow autococker. flatline air system and AA black ice reg. the first shot is low and each shot after the first gets faster untill im back at 300fps. also i get a 30fps shoot down while shooting. which reg should i be looking at for the problem?

It could be any of them. I'd check them all.

Make sure you're stepping the pressures from the regs. The Flatline should be about 500psi and the Black Ice should be about 250psi. Also, the BI is a high pressure reg. Make sure you have the LP spring for it. You'd be better off getting something like the Messiah reg. for your FreeFlow. Also, go through both systems and check the reg. seats and make sure the pistons aren't all dirty and gummy.
