Yes, i know its not an incredible increase but, the power starts to come on a lot earlier and a lot harder. while my max torque is still hitting at about 4k she is now producing about 270fpt at just after 2 1/2k. once she is broken in I'm going to raise the rev limiter to 8 since we're not seeing the hp gains start to drop off till about 6500rpm.
Raising the limiter to 8k will do nothing to increase power as the intake manifold will not allow it (power) to increase beyond 6500rpm. I suggest you find out why the power is low before taking it to 8k regardless of what intake manifold is on it.
Skyeking take it easy we are just letting you know that because of your dyno numbers your down on power. 99-01 cobra's make 320fwhp which means they should be about about 280rwhp stock so with caMs you should be making more. Learn these cars they are easy to learn and work on. Expensive at times but that the nature of the beast. Get a second opinion on the tune. There could be a few factors affecting your numbers. Did you break in the engine to let the rings seat before you put it on the dyno? Cams might not been degreed properly or advanced(not being installed with adjustable cam gears)
Those are better numbers. If the valve guides didn't get replaced that is most likely were your tick is coming from. Ask them what was done to the heads.
