my issue with the thing is that from 70% throttle and up, your throttle body is basically 100% open, which is horrible for any type of racing (excluding drag of course... and even then with high hp cars - mostly 2wd - you need more pedal control so it's bad for that too). if you're full throttle through a corner and you're pushing wide, you have to back off from 100% to 50% or less throttle to get any reduction of power. the useful travel of the pedal is greatly reduced by the thing. the whole product just doesn't make sense. the only thing it does is control the feel of the throttle (and makes its usefulness significantly worse). if you want better "response", mash on the pedal more because that's all this thing does. from what i read, this doesn't improve the response of the drive by wire, it just manipulates the signal the drive by wire is sending so that the ecu thinks you're at a different pedal position than you are.our car is on the list, and some people may want the eco mode. It makes the pedal more sensative you can't tell me you like the drive by wire the r/t is horrible on it, anything to benefit it would please me.
