It accelerates smoother, with more

It accelerates smoother, with more power, and it coast much farther. I like all the improvements that I'm experiencing. I do have a question and that is the mileage computer relates that I'm getting lower gas mileage however, the actual mileage seems like it doesn't prove that is that the computer.

Wish I purchased this sooner

Don't sleep on this delete. Mine works flawlessly, and makes my 2017 Suburban feel like a proper V8. Gas mileage drop 3mpg on long trips, but I'd rather buy more gas than replace an engine.

Works as described

Right from install my truck shift so much better and I no longer have hesitation shifting gears. Fuel economy actually seems to be better running on full time V8 as well. Money well spent.
