We just did one of our performance enhancing upgrades on this customers Scion FRS. The beautiful blue FRS has the automatic gearbox which can definitely benefit from a ECU flash. Faster throttle response, quicker to come into the power, improved top end. This customer had a Perrin exhaust and headers to enhance as well. We did this with our OBDII tuning tool here at our Gilbert, AZ facility. Scion FRS and Subaru BRZ tuning is a great upgrade to improve the 2.0L FA20 engine. Check out the process photos below!
