As stated in the title i cannot find a specific answer to my question. I recently installed a JB4 on my 2015 435i and want to know if i can run map 5 with a stock DP and 91 octane fuel.
I have seen people ask about 93 octane on stock DP or catless DP on 91 octane but never stock DP and 91 octane.

I have the BMS intake, and AWE axleback installed, with the AWE performance midpipe on the way. I plan on getting a CP and DP too but for now was wondering if map 5 or map 1 would be my better option. Thanks in advance for your help.

Hell no.

I'd highly recommend ditching it and putting a proper flash tune like MHD or BM3 on but failing that, stick to Map 1, especially with your combination of 91oct, stock DP and presumably stock IC.

I was under the assumption that map 5 is a auto-tuning map which adjusts based on fuel, mods and temperature. I thought that it would adjust to a stock dp & 91 oct

I've run Map 5 on a mostly stock car (injen intake). I don't see any harm in it. The Auto-tuning maps adjust based on the vehicle parameters and octane. Map 1 just runs at a target boost, while map 5 will adjust boost (not as consistent)
