Big Difference
I have only had this installed for 1 day. It was a big difference right from the start. V8 power at all times and you can really tell a difference. Great item and works as advertised. Feels like I am driving a whole new vehicle. No longer sluggish feeling. It has really opened up the potential of the 5.3 liter.

As Expected
It works exactly as on description. And I've noticed a slight increase in fuel economy after disabling the 4 cylinder mode. It's like a new car. Thanks CARiD.

Good Service
I searched product for get full time performance out of my V-8. I purchased this product and got rid of the "belching" sound that my after market exhaust system would make whenever the engine would switch. Great! It has blown me away.

Improved City MPG, Not Highway
I'd rate this product a strong 2 to weak 3 star overall. It seemed to work the way intended as long as you were under 55 mph. At highway speeds, it didn't seem to make any difference at all, which is where I'd hoped for improving my mpg. When it was engaged, the 4 cylinder mode sounded different than factory 4 cylinder mode & the transmission seemed a bit choppier on shifts. After about 10 days use primarily in city driving, my wife noticed that the vehicle started to die randomly at stop lights or when stuck in non-moving traffic. That's when I decided it was no longer worth any city driving savings on gas, as safety is more important. I rated it the way I did because when it did work in the city, it definitely increased mpg. Maybe I got a lemon off the line, but not worth risking the safety of my family to find out.

Great
Great device for a great price at CARiD. I purchased this device for my Tahoe and it has been worth every penny. Nice device, why I did not know about it before. I think you will enjoy your ride.
