I finally got around to ordering a Fastman TB. It arrived yesterday and I installed it today. I've only put about 10 miles on since then, but I've already noticed an improvement. Better throttle response, better acceleration. I'll be driving several hundred miles this weekend, and hope to also see better gas mileage.

Below are pics of the OEM (left) and the Fastman (right).

very cool................i was thinking about replacing my current stock throttle body with a fastman. if you don't mind me asking...........what did it cost you (the T.B. and S.H.)? keep us updated on how it works!

 

For the 3.9 liter its $250 w/$80 Core and th core you get back when you send him your origonal throttel body back.

 

I don't have the exact amount in front of me, but I think the 3.7 was less than that. I wasn't charged extra for S&H, though I did have to send my OEM TB back (~$7 UPS ground).
