Read the link posted above... The computer will always be the final decision in any event. All the pc does is increase the voltage, and not really by that much... And it still goes through the computer! The PC plugs in at the pedal. Can't bypass the computer. But if you like spending money on something you don't need to, have at it
You are welcome to your opinion. But don't state it as fact for everyone else.
These are fun add-ons. They make a really noticeable difference in throttle response. You can actually hear it as well as see it in the videos that users have posted. If you can get past all the hoots and hollers of joy that the driver's are experiencing.
I think that this will be a fair comparison: We have re-curved distributors for 50+ years. By 2,500 or 3,000 RPM, their advantage is done. After that there is no help in dyno numbers or in MPH at the track. But there is no debate that the throttle response is vastly improved. These throttle controllers have the same affect with a different approach.
Just take a minute and watch a few of the videos that people have made. Do you think that they all are wrong? Or that they are lying? These throttle controllers are fun. They make a real noticeable difference. To deny that is to deny reality. They are not for everyone. But they are for real.
You have obviously not used one before. But everyone else, here and in the posted videos who have, are wrong.
