Stock Fuel Pump & It's Limits!

[NeQX]

Hey, I'm running 24# injectors and 55psi no vac with my hefty cam in order to maintain proper A/F ratio, alot of times when I floor it car will hesitate not EVERY time, but most, and when car is full (with people) and I floor it...it likes to hesitate some more...its almost like RPMS sputter I hit it and it goes slow or I hit it and it will suddenly kick in, I am sure the car is properly tuned. Put down over 300rwhp as you can see in my sig. I am assuming that problem is stock fuel pump can I get some opinions to verify this? what can stock fuel pump usually handle up to?

Thanks, Mike.

Might be your problem I would look for at least a 155 lph pump! Your injectors should be fine although I think the fuel pressure is a little high unless you have done strip or dyno testing to find best pressure for your set up. Put in the bigger pump and play with the pressure is my thoughts!
