I own a 2016 M235i 6MT & have been on the fence of doing an upgrade by adding just a simple Stage 1. Car is stock & owned it from the beginning. Will be running octane 93. I have the habit of driving in Sport mode every time.

Question: After the Stage 1 tune, will driving in comfort mode feel pretty similar to (pre-BMS stage 1) Sport mode? (Minus the stiff suspension & firmer steering)

Any benefit with Octane 93 over Octane 91 really? I'm in Canada (Greater Toronto Area), not sure the quality of fuel here compared to the rest of the NA market.

I am very pleased with the output of the N55 engine already... but it's been just over 4 years of ownership and thinking it's time to do a little upgrade to it.

Thanks in advanced.
