not really a benefit in a big tb on a turbo setup like there is with the m90. m90 needs the extra air cause its a Suck through setup, with the turbo being Blow through, it doesnt need the same diameter for the same power.
Once you reach mid 10's or so im sure it would help you a little. Probably have a little better throttle response with the N* on a turbo setup, but i doubt you would see or feel any gains.
fwiw, gn guys run low 10's all day on a pos 62mm tb. and srt4's run 11's all day in the 50mm's. i know, apples to oranges, but thats over 400whp anyway you look at it
