As stated by numerous others the ECU reflash really pulls your bolt on together nicely and the staff are very helpful as well! THANKS!

Didn't realize how far from optimal the stock calibration was downshifting let off everything about the driving experience improved far easier smoother and more quiet not as hot/cold on/off all or nothing and yeah she's ready for that mustang new redlines like an illicit substance

Definitely helped my 2003 RSX S with CAI,RH,AND EXHAUST. VTEC at 5200 still gives a nice crossover and the throttle response is amazing. I also have a ITR ecu so I will say each have their advantages but other then VTEC they both make the car a MEAN MACHINE; maybe I'll do a dyno comparison one day.

IT DID NOT LOWER VTEC stayed at 5800rpm. That's what I was looking forward to the most. But I still gave it a 4 star because you can feel the power gain, nothing to crazy though. But yes worth the money! BEFORE: AFTER: 04 RSX Type S 14 Honda Si

Best bang for your buck! I had the an injen cai before I got the reflash and it basically just made the car sound better. There wasn't a noticeable difference in power. Now the power band is very even and smooth. I don't have to wait till 6k rpms for power. I even spin tires in 1st if I floor it. Definitely worth the money. I also like how they let you pay the difference for Kpro if you want to do more upgrades.
