What size is the factory SVT throttle body? I'm wondering if a tune would do the same thing (off idle feel).

So I'm going to go ahead & order the 67mm TB and have everything installed at once. Thanks again for your help!
Keep us posted on the sound of the Magnaflow CB.

Stock is 65mm. Doesn't sound like much but Turbo Tom highly recommended it. I'm buying one. It sounds like the back ordered 67mm TB is now in stock?

factory TB is 65mm. And Yes a tune will make a big off idle performance increase. At least on Supercharged. I assume it will on N/A as well.

Nice! My goal is NOT to burn out however. My goal is to achieve maximum "get up and go" for what I am willing to put into it. How is the get up and go with this TB over stock? Whne pushing the peddal, is it still just a smooth press on it? Or does it become very stiff and hard to push down on?

well i don't usually burn out, but when i revv it like i did tonight, a quality tire spin is definitely possible. there was a big big difference and the get up is quite nice. the stock one was definitely slow at the acceleration. the new TB was pretty peppy, without being ridiculously sensitive. they say when you get a new TB, you need to go "re learn" your car....yeaaa no. i was totally comfortable with it right away. i definitely noticed the pickup tho. when in idle, you revv it with the old one, its a slower rev to get to higher rpms, with the new, it gets there pretty quickly. it definitely didn't feel stiff or hard to push down. the pedal felt pretty similar from before, but you just don't have to press down as much. it was an improvement indeed. you will be pleased with the results..along as you put it in right =D.

Actually Stock TB on the SVT is 63mm.

Saw this kinda late. But figured I would pop in and say it for those who read through the thread later.

^^^ yeah I always thought the stock TB tapered down from the opening. CFM build quality products, many i've owned since first production , and have never had any problems with them. The bigger TB wakes the car up i little.
