PEDAL COMMANDERfor Cadillac CTS 2014-2019 Throttle Response Controller Fits: 3rd Gen, Base, Luxury, Premium, V-sport, CTS-V, 2.0L 3.6L 6.2L Cadillac CTS Accessories

I have used these before on other vehicles without any issues whatsoever on two other cars. But I used this on a Cadillac CT 6 and it messed the car up..Causing the engine light to come on and for the car to reduce power to where the car would barely move. I would not suggest using this product on the Cadillac line.

I was actually looking for my 2017 ATS COUP 2.0 and this one came up and the connectors did fit. It arrived the next day and I had it installed in a few minutes. WOW!!! It made the car come alive. It is alot quicker with no hesitation and smoother shifting. On a long Calif. Coastal trip my mileage went from 23 to 32 average mpg and it is set @ Sport 1 mode. The most fun I had on my trip was driving the ATS. I have put around 3000 miles with it and have no issues. I highly recommend it.

If it’s being used on a Cadillac after installation you have to perform the Throttle Position relearn otherwise the car will not drive right just like he was saying
