Map guide as of v5 firmware (selected via JB4 Mobile/laptop interface. Map1 is the default map)

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: Valet map, runs around half as much boost as stock.
Map 5: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.
Map 6: User adjustable map. Enter value of boost over stock by RPM on user adjustment page.
Map 7: 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 8: 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.

Check out this thread. You'll see guys running on map2 using shell 91 and Terry has checked their logs and given the thumbs up.

I decided to pull the trigger and got the jb4 and plugs.

Its not the tune as much as the car runs out of fuel in the e25 to e 35 range depending on mods/boost.

Yep, due to the injectors maxing out. A tune would be required I assume though to make use of the additional timing made available by the ethanol in the mix.

Sure - but he also notes that it varies, and I'm 90% sure he said on here that CA91 is generally ok for map2 - but you have to log and double check. On the web page for the jb4 - Kia / Hyundai Turbo JB4 w/ Fuel Control Wires & Billet Enclosure - they have a dyno for "map 2, 91 octane".

Looking for ideas to make my 2019 GT faster. I'm not concerned about drag racing per se, but I love to drive fast up and down the west coast smashing 5.0 mustangs and enjoy having power in my cars.

This is what I have done so far.

• Ultimate Performance FMIC with cold pipe
• JT intakes
• Velossa Tech Ram Air
• ADD Catch Can
• xForce Varex Catback EVC
• Eibach Sway Bars (rear/front)

I'm just not sure what I should do next and what can give me the most bang for my buck...

JB4 all the way!!!

FYI- Actually a piggyback and even a stock Stinger would take advantage of the added octane provided by using a little e85. WOT runs will allow our adaptable ecu to maximize timing advance & power based on available octane levels similar to how it would going from 89 to 93.

However, you’re right and a chip/tune would be needed to add boost with the additional timing for maximum benefits.
