I would think that the TB mod in conjunction to others such as an air filter and CAI would all work together for some benefit. If you're not a hard core track person, than throttle response would not be much of an issue. But at the track it might mean the difference between accelerating out of a corner a few feet earlier to achieve a higher top speed at the end of a straight.

 

One thing I need to make clear and I didn't. I do not have the Spoon TB, I have the ProFlow.

I did not do a before and after on the same day. I did however get a baseline of my car just for the sole purpose of finding out my mods really work.

In any event, take what I have to say with a grain a salt. 6 or 7 hp for only 600 bucks is a deal on the S. You should jump all over it! You just have to believe your vendor.
