good luck paul but i still dont think you'll gain another 40rwhp from tune, pulley, and TB.

come on at least 400rwhp...

are you staying with cats? catless I guarantee you 400rwhp if not 410rwhp. But I think you should make it to the 400rwhp league.. I sure hope im right.. This cam should surely be comparable to the X1 cam and the x1 should be doing 400s with bolt ons right?

X1 specs : 230 227 .591 .571 112
F13 specs: 230/232 58*/59* 112 or 114

pulley and TB are worth maybe ~13rwhp, some how i dont see a new tune gaining ~30rwhp. im still saying its mechanical and not the tune, it stops making power before 6k. that cam should peak @ 6300 and carry power to 6600 easy.

Ditto. mine peaked at @ 6300 and carried on through. Sounds like it is something mechanical. I had low seat pressure on my springs and my graph showed slight valve float right at peak hp. I made right at 400rwhp even with the dip in hp.

any suggestions guys how do I know if it is mechanical and what would be my first steps to correct it?

As said above. Check the timing dots. Even if they were aligned during inital assembly, just recheck. Also check the cain and make sure it hasnt streched on anyway. Thirdly, if noting is found there, Pull of a couple of springs and check seat pressure.

Did you hook up auto tap just to see what it thinks?
