I agree with RF. The tubing on the BG is bigger but if you continue with stock 87mm TB then it shrinks down. I would at the least do ZR1 TB and maybe even Soler Ported ZR1 TB. I think theirs has bracket that allows for a smooth transition between the throttle body and supercharger.

Will you be getting headers installed too? Reason I ask is the mods you are doing are kinda a waste of tune. You will probably be about 50whp more than current but most of that is Ron tuning and about 15-20whp from mods. As you add more mods the HP numbers go up as they work hand in hand. I would wait until you have headers to install as well to get the most out of the tune. Should be in the 600whp range.
