Common Questions Related to this Mod
Related FAQ answers that may help before you buy or install.
tuning
Can I run E85 or an ethanol blend in a 2022+ WRX?
Not on the stock tune. The VB is not flex fuel from the factory, so ethanol needs a flex fuel sensor and a tune written for it. Done properly it is the best power per dollar on the platform.

tuning
Should I get an OTS tune, e-tune, or dyno/pro tune for my WRX?
Off-the-shelf map for a stock or lightly modded VB - they are genuinely good on this platform. E-tune once your hardware combination stops matching any OTS map. Pro tune for big turbo or ethanol builds.
