Chevy Cruze 2012
It's an okay device but if you're really looking for a true performance upgrade then this isn't the device. It's good for small performance upgrades and small gas mileage upgrades. Not much difference as it describes. Have been using it for several months but now ready for a better program.
Sent me a used, broken item!
The tach didn't work, lots of problems. Been with jet performance on the line for hours. They requested me to return the unit. It appears to have been a used unit, as the plastic for the pins was pierced multiple fold, but it wasn't by my socket (all my pins are still ok).
