Timmy LP pressures

Hi all

My timmy, when running without the LP mod, ran at 300+psi on the high side (dunno how much really, cause I killed the 300psi gauge). I recently converted to the LP mod, and now the high side is at 165-170psi. I guess this low of a pressure means I'm getting a very low shot count, is that right? I haven't shot it that much to notice by myself, but theoretically I guess that's it.

If so, what can I do about it? Is there anyway to raise the pressure to say, 200-210psi? Would that increase my shot count?
What if I change my dwell?

please enlighten me guys

He had to increase his pressure because he used Bobby's bolt. It has decreased efficiency because it fits 'loosly' in the chamber, thus needing you to up your pressure to compensate for the blow back that the bolt has.
With MTN's bolt your theory is right. It fit's tight in the chamber, with virtually no blow back and you are able to drop you pressure. That is why we do not recommend the ligher gen 5 bolt with the LP mod. You might have to decrease your pressure even lower, which will consume more air in the long run.
