Fuel problems...need advice please So I hooked up a fuel pressure gauge on my car today to see what is wrong with it. NA at idle and WOT I get about 60psi of pressure 
On spray at WOT my fuel pressure bounces between 48-55psi 
So my first guess is my fuel pump is having some trouble 
Could this be an injector problem since it is bouncing around so much 
What made me check my fuel pressure is when I am spraying my car starts to backfire really really bad.
Any advice would be nice...thanks.

I would rec. at least a pump you are running out of fuel on the spray. What is your setup...what mods and what hp level? Let me know and I can set you up with what you need.
