    GSXR1000R Flash

    Made an incredible difference on my bike Lower gears are so much smoother than stock especially when going on and off the throttle. Above 10k the bike pulls extremely hard. Definitely recommend this tune.

    I can’t believe how much of a difference this made! It’s like a whole new bike. So much smoother throughout the rpms and way more top end power. Also made my check engine and FI light go off due to the full exhaust. Great job on the flash guys!

    I recommend the flash it makes the bike run much smoother and responds much better with much better horsepower.It is not for the Street it’s perfect for the track. They done a wonderful job in actually doing the research and troubleshooting hands on adjustments and actually taking the time to go back to any errors found and correcting them before sending it back to the customer. Love it!! Love it!! Love it!!!
