the CircIQ moduel went on my Tundra and changed nothing else. The same tank got me to 452 miles, not 386 miles. I quit checking it constantly. Bettter than expected.

This is more about drivability for me. the sports car feels more alive in the first few gears since adding CircIQ unit. This is the kind of response I was hoping the pedal tuner would give me. Good upgrade, not trying to exaggerate.

My 2019 Tacoma is nicer to drive. Tows better, simple as that. Just being honest.

i pull a small trailer and hate when the truck hunts around on hills. it brings the response alive. no regrets here.

I was skeptical and still wrote down the numbers! With the CircIQ module on my diesel, picked up 2 MPG! It paid for itself quicker than I thought.
