Subaru FA20 Upgraded Turbo
This option is for doing a tune on a Subaru WRX with the FA20 engine with an upgraded turbocharger and any supporting mods.
Flex Fuel ($200)
Add the flex fuel feature to your E-tune. This requires that your car be setup with the needed hardware to run flex fuel. If you are not sure, please ask us before purchasing. We strongly recommend an upgraded in-tank fuel pump for running flex fuel and we recommend blending to a maximum of E60-65 for best results. We will E-Tune for all blends from 0-10% up to E50-60% during the tuning process.
E40 Map ($150)
This option will give you a tune for an E40 mixture of ethanol and gas in addition to a regular gas only tune. An E40 mixture is done by mixing half regular premium fuel with half E85 at the pump. It is safe to do this with any modications and even with a stock in-tank fuel pump but can upgraded pump can be done.
Burble Map ($50) -
This is an extra map that will give the car a "burble" or popping exhaust sound when coasting in gear. The feature is active above 3000 rpms and only when coasting (decellerating). The effect and sound will depend on your exhaust system. The more open it is, the louder the effect. Stage 1 cars or Stage 2 cars with resitricive muffling may not be able to hear the effect very well.
