Not cutting you or anything. Don't take this the wrong way.
I would expect more than that from a KB lightning with 15lbs of boost. Do you have the timing cut way back because of running a stock block; or, is that all you could get out of it. The A/F is right where it should be. I'm not saying your truck is not strong. I just think you have some more safe HP in there. Even on a stock block.

I personally think those numbers are awesome. The tuners I have talked to say A/F's up to 12.1 are safe, so with an A/F of 11.5 that tune should be way safe. Remember it is still the stock block. If you don't mind my asking, what does it cost to make the switch to the KB blower?
