I'm sure yours is doing better than mine, since you've got the larger crank pulley. Also you've got an ECU tune. Is that a custom tune, or an out of the box tune? If it's custom, I've heard guys gu-estimate an added 20 hp for the tune.

I wouldn't be surprised if you were pushing 430 hp at the crank.

Take it to the drag strip and see what it'll run. That's a better indicator of hp than any guess work we can do here.
