Kevin brought us his Downshift Blue 2020 Toyota GR Supra to get it sitting right and to get the B58 woken up!
Up first, Matt strapped her down for pre-work dyno pulls to establish our stock baseline, coming in at 337.79whp & 400.56lbft. Then in the shop, to allow the turbocharger to breathe more easily and also free up a bit more of the B58’s exhaust note, Alex installed a down-pipe from Extreme Turbo Systems connecting to the OEM exhaust system, and then to get the A90 handling better and sitting right with the forged HRE Performance Wheels P101 wheels, installed a set of V3 coilovers from KW suspensions.
With the mechanical work wrapped in the shop, Matt strapped her back down to the rollers for Vlad to perform a custom calibration via EcuTek Technologies Ltd. With 93 octane in the tank, and 98° F ambient air temperature in the dyno room, Vlad was able to increase the B58’s output to 444.77whp & 528.79lbft, holding 21psi to redline — a gain of 106.98whp & 128.23lbft over stock! Killer result for this gorgeous A90!
