    I had a 2017 gsxr 600 but after seeing so many videos with the Gsxr 1000 I decided to go for it. I purchased a 2018 Gsxr 1000R and ordered right away the CT full system and ECU flash. After installing the full system and the ECU, my mechanic did a test ride and came back pale with his hands on his face. I thought he was acting so I tried and came back pissed on my pants. This bike is a beast. I couldn’t be happier. I love the performance but the part I love the most is the sound! It’s deep and aggressive and I use the bike as my transportation every day and the sound is perfect not so high frequency but low and loud. I use ear protection just because I’m musician. Highly recommended. The best option. Go for it !!

    Ecu flash with f1 tune

    Got ecu flashed with predator exhaust description says smooth throttle response I do not like the throttle control from low rpms after 4K it is smooth but have to be very careful if riding on dirt roads or driveways.

    @BrocksPerf Reply: The ECU flash removes factory restrictions so that you have all of your power all the time. Because of this, when you twist the throttle, even a little, it will want to go and it creates a much different feel, especially in the lower RPM range where the factory keeps the flies partially closed, that does take a little time to get used to. I hope this helps explain what you are noticing.

    I went ahead and threw this in with getting my exhaust and the power delivery has really transformed my bike. Definitely a happy customer right here.
