CUSTOM TUNING

Custom tuning for B58 Gen 1 is available for pump gas, race gas, full E85 and E85 blends, and methanol injection. Results will vary depending on hardware modifications, the fuel used, and the weigh/traction of your particular B58 model.

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 A90 Supra HPFP is a great bolt on upgrade that will allow for even better performance with e50 or greater ethanol blends. 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 B58.
