For the right amount of money, we'd do almost anything.

It would be FAR cheaper for you to just state the problem more clearly so we can help you over the interwebz. By the wording of your post, I assume you have a meter, no?

yeah i do, and i have a 6"x1/2" meter pipe going into a 17x4" chamber, currently i have the pressure set at two shots of 40 psi amd the first time i use it i get a decent launch but as i keep using it, it continues to decrease in power. then i let it rest for a day and its fine again, but i thought propane was supposed to cure the efficiency problem

do you vent the combustion gases after each shot?
