Worked just like you said and easy to install. Plug in and doesn't effect the engine light. Great!!!

Great product

Reviewed By Luke B (LANESBORO, MN) Reviewed for a 2011 Chevy Silverado —8/9/2017 10:43 AM

Love the device I got. More noticeable power and better fuel mileage. Was skeptical buying at first but so far so good. No more hesitation going between 4 and 8 cylinders. Love it, only complaint is the blue led light on it.

Easy Fix

Reviewed By Patrick S (Grand Forks, ND) Reviewed for a 2010 Chevy Silverado —8/5/2017 1:10 PM

This product is great, put it in at 80,000 miles after 3 sets of spark plugs. Runs great and should be the long term fix I was looking for. No more hesitation from 4 to 8 cyl and gas milage seams better in town for sure.
