MPGs/driveability

It removes DOD, improved drivability, no studder when slowed, and have to accelerate. Mixed city/short hwy, mileage is lower. Overall the performance is no hesitation when slowing or stopping. Haven't experienced uninterrupted highway driving since install.

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.

Great product

Fantastic. Does what it was designed to do. I read some reviews that it may cause your battery to die. I have yet to experience that and sometimes my suburban will sit for few days. 5 stars!
