Prior poll was started early in the Stinger/JB4's development, and before the remapping (so Map 4 was valet vs. Map 8 now). So what map & fuel is everyone running in 2023?

Map 0: JB4 disabled
Map 1: 4psi over stock peak tapering to 2.5psi at high RPM. Default performance map suitable for all 91+ octane fuels.
Map 2: 5psi over stock tapering to 4psi at high RPM. Suggested for 93+ octane fuel.
Map 3: 6psi stock tapering to 5psi at high RPM. Suggested for high quality fuel including unleaded race gas, ethanol mixtures up to 30%, or high quality octane booster like Torco or Boostane.
Map 4: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.
Map 5: Up to 7psi over stock but without top end taper. For unleaded race fuel use and bolt on modifications. May not be suitable for E85 mixtures due to high fuel pressure dropping. If using this map on E85 you should be experienced at reading your own logs and evaluating ignition advance and fuel pressure.
Map 6: User adjustable map. Enter value of boost over stock by RPM on user adjustment page.
Map 7: Progressive WMI (water/meth) map. Increases boost as a function of methanol flow & methanol boost additive. Holds boost low until WMI is flowing to avoid tip-in knock, and reduces boost as a function of WMI flow in the event of interruption like running out of fluid, leak, or component failure.
Map 8: Valet map, runs around half as much boost as stock.
 
Add BMS HPFP.
 
Is there a way to vote twice? I would choose:
91 / map 2
E30 / map 4

I guess it's more E30, so I'll pick that, but 91/map 2 is still 20-30% of the time, I would say. Except for track usage, then it depends :-)
 
DD is map 1 because of 91 octane in California.
At the track, WMI map 7.
 
From interior to exterior to high performance - everything you need for your Stinger awaits you...
Just found some E85 near me and now trying out Map4 with 93 mixture. Really does make a difference, the power feels unreal from stock, just beefy, and stock was pretty fast itself. Now I can get away from Boostane and run E30. HPFP is next on the list.
 
I’ve been running stock tune with jb4 disabled because of Winter so can’t wait to fill up with some e30 and put map 3 back on. Seeing a lot of performance cars as the weather dips up into the 40s finally.
