Out Of Fuel

[greddy_skyline]

Hi guys and girls,

Im having some problems with my fuel system. My car on the dyno is making 300 RWKW but if the workshop tunes it more than that the car physically runs out of fuel. The fuel system spec's as follows

- New areomotive stealth 340 intank pump.

- Reconed 8 (something) cc injectors.

- New fuel filter.

- Stock fuel pressure reg.

The fuel pump has been wired up right using 10g wire and a 30A relay as per instructions and has been install and place on the bracket so it reachs bottom of the tank.

I called the guys that sells the pumps and said that they are happy to test and replace if needed but he commented that they haven't heard of a faulty one nor did he say its not possible and that that pump should be ok for the job. But im in the process of elimination. But i want to know how much can the stock fuel reg make?

Any help would be great!

Many thanks
