22 rwhp pickup. That doesnt look right. I would take it to a different tuner, just to compare.

Looks pretty good because you gained 22hp going from LS6 heads to ported stock heads.

Oop's, just noticed the FAST. I'm going to say the Cam is killing the power.A 224 intake is small and the 42x hp is actually good for a 224 Cam and the intake is probly doing nothing until the Cam is swapped.

I think the cam only numbers are good but not with heads and fast.

Get a MS3 cam & you will gain another 25 RWHP easy.

I don't know about that, there are much better cams out there to choose from that have much better power curves. Some more intake duration on that cam and it would be good.

Are these LS6 heads?
Are they new?

I know Vengeance has made 480 RWHP with these heads and Fast intake and one of their cams. Sounds like the cam may be wrong, but that is a ton of lost power.

*edit* Just did a search and see that you bought the heads from an individual. What is his name?

I am with you on the cam being wrong Brian. A 228/232 sounds a little small for what those heads should flow. Who did your tuning?

I made 412rwhp/394tq with PRC Ported 243's, 228/232 112+4 and LS6 intake on a LS1 block with 120k mi on it. I think you're leaving power on the table somewhere. Slowhawk is real good at what he does...sounds like he's betting on the cam.

It's hard to say.The #'s aren't too low for a 228 Cam setup,atleast on my dyno. Could be tuning to squeeze out 5-10 more hp or the dyno could read low. I know having the heads milled to 60cc would be better.
