I purchased a stage 3 for my Subaru outback, after driving over 700 miles I only noticed a 2 mpg difference, throttle response seemed better and so did the power . I reached out to the company via the chat and the company's response was quick , they suggested a reset ,which did not work then offered to exchange it for a different one . After receiving the new one and driving over 150 miles I only noticed 1 mpg better . After all that the 30 days has expired ( go figure ) .
Overall the chip is a failure does not perform as advertised, don't waste your money.
