Subaru FA20 E40

This option is for doing a remote (email) tune on a Subaru WRX with the FA20 engine with a stock turbo, any mods and using an E40 ethanol blend for fuel. E40 is a very optimal and easy blend to do on the FA20 engine. You simply use half premium fuel and half E85 when filling your tank. Our tuning can handle the varience in ethanol blends you might encounter from summer to winter and your engine will run consistent as long as you mix half and half on each fill up.

 

Estimated power:

320-350 whp / 320-340 wtrq depending on modifcations

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.
