I call B/S on this too. 7 hp I would notice. I have raced aginst car with chips and 7hp is not gain people see. It just is not. 2-4 hp is possible that is all. The only time a chip made a difference on track was one that was custom tuned and developed on a dyno for a particular car. This chip did not even make alot of peak hp, but improved the mid range some. However that was not an off the shelf chip. It probalby took 8-10 hrs of dyno time to perfect the map for that particular car to see those gains.
