So I inadvertently loaded the 91 octane version of the Stage 1 tune a couple of weeks ago and the power was amazing. I've been meaning to load the 93 octane version and hadn't gotten around to it until today. I didn't expect much a difference but the idea a few extra ponies was tempting.

I'm totally blown away. Perhaps I'm missing something. Can someone please quantify the actual difference in terms of HP/TQ between the two?

To me it almost felt as drastic of a difference going from stock to 91 Stage 1 as going from the 91 Stage 1 to the 93 octane version.

What a screamer. Holy hell.

I heard good stuff about the stg1. I bet seanWRT can explain the difference between 91/93 octane.

Does anyone track with this tune and/or has a dyno plot?

Sub-zero Octane difference between 93-91 - the timing is lowered by 1-2 degrees and boost is lowered by 1-2 depending on rpm. Estimating difference is about 20-25 hp/tq

Interesting....I didn't expect that much of a gain. What a pleasant yet brutal surprise. Thank you

I just did Stage 2 93 octane BM3 last month, had a piggy back before. The torque is a monster in 1-3 gears.

Do you have any additional components to support the stage 2?

Rocket ship! Have you upgraded tires? I feel like going a bit wider with a softer compound would be helpful

I have Michelin Pilot super sport for the winter I use Continental extreme contact. Traction isn't too bad kicks in a little in 1st and second.
BM3 Stage 2 is a beast bro, Bootmod3 is the best mod out there for BMW.

The power must be crazy. Thanks for the info! Yes, I'm liking BM3. The interface is also very easy to use. Great product.

After hearing all the great reports about the CS+ map I decided to load it first. It definitely was a performance upgrade you could feel in the seat of your pants. After a couple days, I was board and thought I’d try the stage 1 93 map. What a kick in the ass! Not even remotely close IMHO!

Makes me wonder what a custom E85 map would feel like? I’ve said this before & I’ll say again here. What a wonderful time we live in. Just a couple decades ago, an increase in power that’d equal this simple flash would have meant.....heads off, ported & re-worked, camshaft replacement, intake carburetor upgrade, headers ....sweat & tears. Ruined fuel mileage. Drivability would never be the same. Smell like fuel all the time. Yuck.

: seriously, the Stg 1 93 is ludicrous. I wonder when the BM3 folks are releasing the M2C stock map so it can be flashed back in case of service or dealer visit.

You should already have a copy of your stock map. BM3 and most other flash tunes take a copy of your stock map during the unlock process.

Thank you all for these updates! Keep them coming. I can't hear enough about how crazy and fun a tuned M2C is. I will work up the courage to do it myself I hope. Until then, I live vicariously through your tales.
