Sorry for the newb questions in advance.

94201

No matter what, gapping is recommended. But you can try to run without a tighter gap and see if there are no issues in your logs. I didn't regap my plugs until I started seeing timing issues.

Perfect - you the man...thanks! Going to install these and start grabbing some logs next week. Hope this makes things a touch smoother. I'll let you know my feedback.

boosted said me that NGK need to gap 0.025' but Champions plugs to 0.022'. Is it true? I want to install now the ngk plugs after remap with MHD stage2

Again, if you run them, run logs. No one can give you a magic number. Gap too tight and you lose efficiency. Gap too loose and you lose spark. Everyone can tell you what they did, but that does not mean it'll be perfect for you and your setup. I ran my plugs at stock gap for a while without issue. YMMV.

The typical recommendation across the board is 0.022" for 93 octane. You can try less if you wish. If your logs look good, then it's running well, and no one else's suggestions matter.

NGK 94201 installed with my MP tune. I feel the car performs better, sending log to MP for confirmation. Per Alex (MP), 0.025 should be suffice for NGK vs Champion, however during the process I accidentally set to 0.023

and then continued with the rest.

Has there been any confirmation by Alex on that NGK 95248 plug he recommended? I hesitate to order it because of the different spec size. I'm gonna play it safe and order the 94201s for now.

94201 has been confirmed for 340i while 95248 for Supra.

Run them as is. If you see issues with timing, reduce the gap.
