I got the 70mm TB. I like it, nice crisp response. It was real different the first couple of times I drove my car though. The throttle is pretty touchy.

 

well first get a bigger maf if this mod isn't done first your wasting your $$$ on the T/B

 

I have a bigger mass air flow and the 75mil t/b and the trickflow plenum and I noticed a decent difference. The t/b does nothing without the plenum.

 

I have the Trickflow Plenum and 70mm BBK TB. Buy both together and put on at same time. 75 w/Densecharger seems like it's choking on too much air, but 70 feels just right. If you have short-ram, go 75. Full cold-air go 70. Also you might want to check out www.mustangtuning.com and check out the plenum spacer they have there. It's cheap and gives you 3-5 hp most of the time. Definately felt a difference when I put on my TB/Plenum combo, but I did it all at one time.

 

Choking on air? I've never heard someone say that before about your setup. How can you tell?

 

Maybe it's because it's not exiting fast enough. I'm not sure but it seems that way.
