Anyone still thinking about the reflash, don't wait the reflash completely change the way the car run. Throttle response is more aggressive, I got a 06+ intake mani with CT icebox, thermal mani gasket, and a fastline test pipe. The car pulls alot harder then before between 2000-7000 rpm is a whole complete different car.

Great value for the cost to benefit ratio. Doesn't add a huge amount of peak power BUT makes the car much more enjoyable all around..and definitely more eager to rip through 1st to 3rd - redlining them all of course! And I could be crazy but my mileage seems better but def as good as before but with the car being much quicker. My car is stock otherwise..looking to add an intake next which should further enhance the Reflash and the cars performance.

Besides road noise, one thing that has always annoyed me about the TSX Auto, is the transmission always seems to stay in too high of a gear, and the engine just didn't do much until it hit 6000 rpm. This fixed that by providing more power sooner, as well as I notice a 3% improvement in fuel economy. Passing without needing to use the sport shift mode can be done with more confidence. Note that below 4400rpm the car seems the same. Turnaround is very quick, and Club RSX handled the order and questions with no nonsense.

**10/2/2009** I have had the reflash on now for a month and I love the power& the way the car picks up speed much faster then before. When in the high RPMS you can just keep pushing it and it keeps going it really feels like a different car. The gas millage has not changed it has stayed the same or a little better. I have Injen CAI, Comptech header, and Tanabe SHM exhaust and it really woke the car up even more with he reflash. The extra torque really helps on hills on my way to work no more need to downshift. Overall great upgrade for this car and worth every penny.

All I can say is wow! My god! I have an 06 TSX with CAI system DC 421 headers, NGK spark plugs and a hondata heat shield. I just got my car back from my boys shop. I took it for a test drive and coming out of first gear the the car through my head back. Its like a totally different car. Is getting this reflash the best bang for your buck? yes it is. I think anybody with a TSX should get it done if you want some serious power. The thing is I'm not done with my car. I still have to put in my exhaust system. I wait to see what that does for me
