My first numbers are 536/491. But we have somethings to do with the air intake before we do any more tunning. The blackwing wasn't working well so we make shifted an airaid to get these numbers. We will be doing a different intake then more tunning in the next day or so.

Had we been able to run more compression some where around 11.7:1 would have got close the the 550/500 mark. We may be changing the cam for a larger one in a couple weeks. If I drive it and feel I would like a bigger cam. That should also put us around 550whp. But we will see how she drives first.
