does anybody know what the stock throttle body size is on mmy 2007 GT??? Will changing to a bigger size help with throttle response? and will it increase HP? im sure a re-tune will be needed right? any imput and any results anyones had would be helpful.
thanks.

Tune, cai, long tube headers, and mufflers are your best bet. The gains on new TB's seem to be pretty low.

You will get a lot better throttle response difference from a re-tune as the ford programming has a torque management system to limit how quickly the engine will produce its power... It feels like turbo lag to me.
With my Evolution tune... its immediate, like the old cars.

Don't waste your money on a 62mm TB. Performance gains are unnoticeable and the throttle response isn't much better. The 55mm is fine unless you're running forced induction.

That's good to know, bro...I'd been eyeing that BBK that you have.
So, would you recommend UDPs as the next, easiest, biggest bang for buck mod?

I'm not saying the BBK TB is a bad product, just that I see no significant improvement in HP or throttle response. I do expect it would help a s/c vehicle. Pullies are a cheap, fairly simple mod for a quick 10 hp recovery. Just make sure you get a good set with an SFI approved balancer to ensure your crank pulley doesn't wobble.
2007 gt stock throttle body size??
