Race gas I believe, not sure if it's blended with 93 or not.

With 93 you can run map 2 and 3 however it may pull boost and timing. E30 equates to around 94-96 octane so you will get better results adding in the ethanol. Correct adding higher octane just go on the jb4 mobile app and switch maps on the fly.

Great power, but that graph doesn't look very good? Looks like there was some oscillation in stock form, it's a lot more pronounced after the JB4. Wastegate issue maybe?

Dumb question...I've never ran E30 in a vehicle. If I got a jb4 is there anything else I'd need to run E30? I'm assuming if I were to be traveling and E30 is not available I can knock the tune down to E30 octane and be good?

E20-30 should be within parameters of the stock fuel system, anything higher you would need to log and see where your HPFP starts to crash and/or you lean out and get knock.

According to Jordan at RKTunes, it’s from the jb4 while in sport or sport plus modes because TB oscillations.



I’m waiting to install mine until I get my first service.

I wonder if it'll adapt after a while and smooth out

I really don't know, but he's adamant on using the efficient/comfort mode.

Does comfort mode allow you to modify driving settings to match “sport” while still being in comfort? I haven’t picked mine up from the dealership yet and have not played with it.

Yeah you can set everything else to sport but leave the throttle mapping in comfort.

Yes, the only bad part is the exhaust valve is basically closed in comfort mode.

Ummm I’m sure you can program the valves to open under the M1/2 settings or just use the actual exhaust button in the center console that would open your valves regardless of whether the comfort setting is selected

Valve programming is directly tied to the drive mode as they are not just open or closed. They work like a throttle body.
