The claim of +66 HP is a bit misleading, when in fact the true HP gain is only +10 over the max stock HP. Having said that, it's still a worthwhile product due to the vastly improved throttle response and drivability. And the removal of the annoying driveline-protecting delay of power during shifts makes this programmer worth every penny. As an added bonus, I've seen an improvement of 0.5 MPG in AVG fuel economy in the two weeks I've used it, and with premium gas prices as high as they are, every little bit helps.
