    The Brock Flash ECU works exactly as advertised on my 2017 GSXR-1000. I combined the ECU reflash with a Predator Exhaust, Power Commander V with Brock's mapping, and the Sprint air filter. As outlined in the Stock to Brock series of videos, the gains in power and acceleration are impressive, to say the least. These guys will go out of their way to keep their customers happy. In my opinion,anyone wishing to seriously increase their Suzuki's get up and go would do well to consider Brock's Performance Products.
