Again, new track times.

Thanks,

For my fuel system I have an in-tank 255 lph pump, all stock lines and rails, 30 lb injectors, and a Kirban regulator.
I am running Sunoco 94 for gas, and spraying with only 10 degrees of ignition advance.

My fuel pressure hits 100 psi on the up-shifts, but drops when at WOT. I thought the stock lines and rails were good for 600 horsepower or so, and I know I am nowhere near there. Funny thing is that I am burning plugs WORSE now with the 30's instead of the 24's.
I can only figure it has something to do with volume vs. pressure. Maybe the 255 pump can't keep 30 pound injectors fed at 90-100 psi?
If this is true then I may have the same problems with a wet kit.
