And boring the stock IM to match the TB.
I had one on my previous car. It acts the same way I explained. You have different settings which will adjust the throttle response to be more sluggish or to react quicker. It's kind of redundant because you could do the same thing by just pressing the gas pedal a bit harder than you're used to...
To put it simply, when you press the gas pedal at about 25% of the way the throttle controller will make the computer believe you are pushing it 50% of the way or vice versa. I'm not sure if you can adjust the response of the throttle to be more sluggish though.
