Well now that we have a tune available for the F, and RRR tried to use a bigger TB and could not get it to make more power. I wonder if it was because of the maf restriction ( size) or air -flow in the intake runners/ heads, I remember seeing some ported intakes at one time http://s148.photobucket.com/user/boo..._1837.jpg.html http://s148.photobucket.com/user/boo..._1845.jpg.html

I wonder if this combined with a bigger TB ( either a bored over ISF ) or a RCF with a adapter plate would make some good HP/TQ gains

How about the intake manifold!? The GSF is different than the ISF. Is that one of the changes that help the GSF produce 467hp vs the ISF 416hp?
