2012 Chevrolet Silverado 5.3L Fast delivery from autoanything.com. Judging by seat of the pants this programmer does a great job. I have not pulled a trailer yet. Not sure about gas mileage at this time. Only used 87 octane tuning so far. This programmer has some tuning features that I did not see on the Jet Performance website, it has options to tune for a free flow exhaust and/or cold air intake. Since my truck has both I tried with and without the options, it does make a difference.
