I decided to do a little more work on the stock 2018 Golf R before adding parts.
You guys asked for an E30 base tune, so here it is! This car is still 100% stock in terms of hardware. I filled up with 4 gallons of E85 and topped off the rest with 91 Octane. This equates to E30-E31. Then I spent a few hours dialing in the tune.
This chart shows the stock baseline, the new EQT Stage 1 Base Tune, and the new EQT Stage 1 E30 Base Tune. Both tunes run a peak of 27psi, but boost tapers in gradually and tapers out up top.
With the E30 tune, we're now looking at a 44% increase in power from stock. This is really amazing considering this is done on all stock hardware with just a little tuning and a splash of octane.
