Quick question about increasing fuel pressure

[theother1wstolen]

My car has really seemed to have poor low end power lately but good top end, and i wanna rule out the injectors. what can i safely crank up the pressure to without screwing up the factory injectors?

I'm assuming you have a fuel pressure gauge? What are your pressures with the vac line on and off. That's all you need to do to test. If your having low end power issues, check your timing and make sure that the butterfly valves open and close like they are supposed to.

Why would you do that? Cranking up fuel pressure is going to cause you lose more power due to the motor running richer.
