Custom JB4 ECU Tune (0-60mph TESTING) - Noticeably FASTER!?! // MKV Toyota GR Supra

How much quicker does a CUSTOM ECU TUNE make our MKV Toyota Supra project car accelerating from 0-60mph now that we have a custom JB4 ECU tune? We'll compare our baseline 0-60mph Testing from our 2023 Toyota GR Supra 3.0 Premium to today's acceleration tests using our Dragy Performance Meter. As our newest project car, the MKV Supra is only starting on it's modification journey to add additional performance, backed by DYNO proven increases in power (horsepower & torque), and supported by acceleration tests, including the 0-60mph test, and 1/4 mile drag racing to determine if our power adders are indeed making our SUPRA faster as performance modification manufacturers claim!?! Our next step is to get the Toyota GR Supra on the DYNO to find out how much horsepower and torque the Burger Motorsports JB4 Custom ECU tune from Jesse DaBears of 1FastSupra produces before we start installing and testing various Toyota Supra performance modifications!

*SUBSCRIBE TODAY...*We'll be reviewing GR Supra modifications, walking through how-tos, mod installs, taking the car to the dyno to test horsepower and torque, testing the Toyota Supra's 0-60mph and 1/4 mile acceleration, and finding out if the most popular Supra car modifications such as an air intake, exhaust, downpipe, ecu tune (ECUTEK, MHD, BM3, JB4), etc. really does add the horsepower car performance part manufacturers claim!?! We'll be using our 2023 Toyota GR Supra 3.0 Premium project car as our test Supra to test all of our Supra modifications.
