plenums/Tb's are a waste of money IMO. You can port and polish the stocker for free and get the same results as an aftermarket one. That'll save you at least $200, and you can use that money for gears

I've got an accufab with 70mm and you can feel minimal gain....

I have a BBK 75 mm TB and a Accufab plenum. Yeah you can feel a little more go...

I felt a better throttle response, but not much gains.

I have a BBK 75mm Plenum and BBK PowerPlus 75mm Throttle Body. My car was more throttle responsive with these upgrades and I could feel a slight difference on the top end of a gear (i.e. 4500+ RPM). Other than that, no major difference. I'm sure now that I'm spraying it would be a much more noticeable difference between the stock parts, but I didn't add nitrous until after these upgrades.

I have a BBk throttle body and UPR Plenum. Looks nice, idles perfect(once I got that sorted out) and there was a small but noticeable gain. The intake noise is meaner and throttle response improved.
