It will cut fuel at 7,000 RPM from what most people say. Get a good tune, and you can do anything.

I don't know why anyody would think that was the limit. I have used a high impedance 72lb injector, and understand there is now a bigger one. L J makes an injector driver interface that will drive any injector you want. Just need to stay under 7000 or so. I made over 700 rwhp, through the cats, shorty headers, smooth idle, on a very nice driving blown '94 Vette with the 72 lb units. I should say I only tuned it, Tom Nelson built the engine.

Some people must just pull stuff like the 650 hp limit out of their butts. I don't know what L J makes with his now. Plenty, for sure.

I don't know the program the guy I know used, but the car is wicked. I can't wait to see what it does with the new motor.
