Great video and thanks for sharing your knowledge with the community @ Strat_FRS
Both e85 and the header provided a nice gain, but the gains don't seem to stack unlike the first gen.
In terms of how the ECU works, are you seeing much difference in the second gen vs the first gen? I saw someone mentioned that the knock detection has been improved? What are you seeing?

The strategies used are very familiar in terms of what Subaru has been doing for years on this platform and their turbo platforms. It definitely looks like from the factory they were quite a bit more aggressive in the calibration than what we have seen in the past and this is why the gains don't quite stack like they used to.
Of course the more parts you add, the more you deviate from what the calibration was designed for and the more you benefit from tuning.

Yeah that is what the HKS GT-Spec headers did for my first gen, especially after a tune. I can only imagine the extra bump up in power and torque for the 2nd gen, it’ll be a reasonably quick car.

We have a set of Tomei headers we tried on the stock tune and they added a bit torque dip. I am debating if we should put those back on and tune or get a different header on there that is equal length and popular for the platform to dial in. |
