Not sure which 2006 Volkswagen Jetta Performance Chips & Programmers are right for you? We have over 559 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Matthew J from Louisville, KY said, "I cannot speak to the performance or tow settings of the Superchips Flashpaq Tuner, of which there are two, but I can speak to the fuel mileage saving feature. My around town mileage, for my 2007 F-150 King Ranch, has increased from 14-15 to 16-18 and the highway has increased even more dramatically. I have, at least once, maintained 23.5 mpg over a 20 mile span and regularly average 19-21. To be sure I drive to save (I'm probably the annoying guy you pass doing 62 mph on the freeway) and am very cognizant of the mpg; but with today's fuel prices (with 1 mpg difference meaning approximately $25 over every 1000 miles) I don't know who cannot be conscious."
