I bought this PCM mainly for the mileage gains and it has helped somewhat. I don't have an exact figure for it but I have been able to squeeze more from my tank. This product really shines in the performance aspect. When driving normally, shift-shock is almost non-existent, and at full throttle, shifts are firmer and a power gain is very noticeable. The ride as a whole is much smoother, and has noticeably more torque across the RPM range. I highly recommend this product.
