im running a supercharger with 440cc, getting tuned with osirus and I'm having problems with my walbro 255 pump, Im at 73psi witch I understand is too high. When we step on th gas during the tune, my pressure drops. Was there some i was suppose to modify when installing the pump or modify in the pump itself. Shawn church said there was something i need to modify in the pump to make it bypass it's pressure but wasn't sure how to. Can anyone help? I would appreciate it.
thanks
thanks
