2005-06 Mustang V6 Throttle Body (not spacer)

I actually called them about it a few days ago.

Spoke with Chris at Blowby racing, pretty cool guy. He said the TB is expesnive and will be in the neighborhood of $400. He said the company that makes it is claiming 11HP gains, but he did tell me this. He said Blowby will do a another dyno session with a custom car once the first units arrive and let me know what the real gain is. He said the first shipment will arrive the 27/28th of this month, and a dyno session will follow within the same week.
 
If you want a bigger one, buy the Zabtech. It is a machined out factory unit (to 68mm) with a custom throttle plate and shaft. Comes with all the eletronics attached so it just bolts on and plugs in. I use it, still $300+
