2017 GSX-R1000 S2B: Episode 7 (Part 2) - Which is Best? ECU Flash vs. Power Commander

You asked – we delivered. Brock continues Episode 7 with a shootout between the Brock’s Performance Stage 1 ECU flash and Power Commander PCV (tested in E7 P1) vs. that exact PCV map imported directly into Gixzilla’s ECU because the Internet says, “That’s what you do!” Brock goes through his typical painstaking detail to keep the results as nonbiased as possible, while showing his tuning steps along the way. Is the Internet correct? Do we live in a ‘drag/drop/you’re done’ world? Check out Episode 7 (Part 2) - ECU Flashing (ECU vs. PCV Fuel Tuning Shootout) now.
