Throttle Response Controller WAK-520 for Chevrolet Camaro Tracker Spark Cadillac ATS CTS CT6 Electronic Throttle Accelerator Upgrade Chip Potent Booster

A little better than expected. No issues after a month. Plug and play. I keep mine at 2.3. I haven’t tried anything crazy. Same thing another website has for triple the price with a different logo on the front. Definitely makes it easier passing on the interstate. MPG hasn’t changed much.

Device is easy to install even for someone who is less than mechanically inclined. Provides much quicker acceleration, with numerous settings to fit your desired need.

I have bought multiple times from this same seller and they have yet to do me wrong in any way. I have bought this type of item(xtros) from this seller multiple times as well. The product is as described as always, it does what it is supposed to do, it's the cheapest one on Amazon, easy to use and easy installation. Thanks.

Once you find your optimal setting it works really well. Shifts were a little hard till I found the sweet spot for my V8 Silverado. The only thing that could be better is the takeoff response. It’s better than factory but still delayed a bit. Highway and interstate it’s very responsive. For the money I’m impressed.

After having installed this my car immediately went into limp mode and would not accelerate. It is 10x better to just get your car tuned for extra performance.
