That sounds like the throttle body is too small, or it has a restriction in front of it.
I definitely need to do some testing on the dyno. I have a volant CAI with a 4" silicone tube (MAF'less) to a 90mm UMI throttlebody. I think it maybe the CAI, but not too sure.
wow i would have thought som e results would have been posted by now...must be real busy...
There are some results on the vet board.
With the 102tb about 5/10 peak 22/22 under the curve.

Stock LS2 Bottom L92 Top End couple with FTI cam that is supposedly all wrong for L92 heads (thanks Ed Curtis) and a Yank SS3600 stall.
And a bunch of other "stuff" that I won't bore you with.

What fuel rails do you guys run with these part numbers would be great? I just got a fast LSXR 105mm for a friends C6 LS3. Will the stock T/B fit with no issues or should I get a bigger one? Thanks guys.
