Wow, those are good numbers... FP HTA68 is still a possibility... I think the biggest differences with his setup over mine are:
Grimmspeed intake manifold
Grimmspeed TGV deletes
Grimmspeed throttle body
Grimmspeed EWG up pipe
He's put some money in to it for sure, but it's paid off.
Looking at the porting that Grimmspeed does when doing TGV deletes, it's easy to see how that would be beneficial. Can't really port plastic that well though....
