( F80PAUL ) B58 Gen 2 2020+ G20 M340, X3 M40i, X4 M40i A90 A91 TOYOTA SUPRA CustomROM TUNE

Custom tuning for Supra B58 is available for pump gas, race gas, full E85 and E85 blends, and methanol injection. Results will vary depending on the fuel used and the weigh/traction of your particular Supra.  While full E85 tuning is possible on the B58’s stock fuel system, we have found that an E50 blend produces the best overall results because it allows for more boost while still retaining good ignition timing. With E50 on stock turbo you can expect 470+whp on an average reading Dynojet in good ambient conditions. For best full E85 results we recommend adding methanol or port injection. The Dorch Stage 2 HPFP will allow for great full E85 performance. Another great way to supplement the stock fuel system is with methanol injection. 500+whp can be expected with e85 + meth on an otherwise stock Supra B58. These are results that can be expected with stock turbo on an average reading Dynojet in good ambient conditions: • 93 Octane Pump Gas - 420+whp • 93 Octane Pump Gas + Meth - 480+wh
