i have a used marq 6 that i just picked up recently and noticed that it had come with the musashi 8 board in it. it worked perfectly on semi-aotu, but when i changed the firing mode to psp ramping the air effiancy didnt seem to be as good, and balls were dropping off. i dont know whats up i just need some suggestions.

Clean and relube the hpr and engine assembly.
Also, what tank are you using? The tank reg may not be recharging fast enough.

The problem would be with the regulators or engine o-rings; not the board.
