I have a 2015 228i with the M Sports package and I recently installed new NGK OEM spark plugs, new MAD intercooler and charge pipe and flashed with this map attached. Using 91 octane California gas.

I assume that’s the correct map I should be using?

According to the site, I should see a 48% HP and 54% TQ increase?

So from stock 240hp/255tq I should be at 355hp/392tq? It doesn’t really feel like it though.


edit:
Nevermind, I was stupid and looking at the wrong spec, I should be looking at:
N20 (low-compression 28i)
Stage 1 91 octane: 16%HP / 20%TQ

So for me should be 278hp/306tq.

Now that feels about correct.

even then, on stock turbo you wont see any numbers close to 300whp without a custom tune, on a stage one tune you prob are getting around a 20hp gain. I would recommend using the bm3 ACN maps since you are in CALI. As a cali resident the gas quality here is just piss poor.
