Just curious as to what this thing actually does and what gains to expect, if any.

 

IMO, NO. It does not give you anymore HP or topend. It simply increases throttle response. It fools your computer into thinking that you are at a differnt throttle position that you are. Let's say you are at 15% throttle, it will fool the computer into thinking you are at 25% throttle. However, at 100% throttle, it does nothing. So what is the point? If I want to be at 25% throttle, I can just push the gas a little harder. I feel your money could be spent better elsewhere.

 

In my automatic (no torque) it was nice. I don't think it will be worth a damn in a manual.

 

get a $20 weapon R throttle wheel, you'll get the same feeling.
