How much wheel HP and torque can I expect if I unlocked an 2023 LCI m340i xdrive and did the following:

1- just a flash tune, 93 octane pump gas

2- flash tune + high flow catted downpipe, 93 octane pump gas

3- flash tune + high flow catted downpipe, E85 fuel

Note that the car already has the AWE touring exhaust installed.

Thanks!

Stage 1 91 octane: up to 18% HP / 28% TQ
Stage 1 93 octane: up to 21% HP / 30% TQ
Stage 1 E30 octane: up to 28% HP / 34% TQ
Stage 2 91 octane: up to 22% HP / 33% TQ
Stage 2 93 octane: up to 25% HP / 35% TQ

And what power increases could be expected but a JB4 on maps 1/2/4 with stock downpipe and 93 gas?
