BM3 GTS Tune vs OEM comparison

NCG80M3 · 06-01-2020, 06:17 PM

So I had the opportunity to do a baseline dyno and compare it against the BM3 GTS tune. I was able to achieve an average increase of 40hp and 40tq.

Cool! Looks like a healthy s55

I run the CS tune daily and a ~40hp gain over feels about right.

i've always been curious how much power these stage 0 tunes make, thanks for providing dyno numbers.

Thanks. For a Stage 0 map it feels a lot better on the road.

Nice and thanks!! I was wondering how much it picked up. I flashed the GTS tune and have had it flashed for a few weeks.

I am too chicken shit to flash the stage 2 flash without a crank hub

There is a Stage 1 in between, BTW.
The GTS tune is considered a Stage 0.

yeah but you only pick one with the license and since I have catless downpipes i selected stage. Stage 2 is only 2/3% lift over stage one so that is the reason i selected it and I am also planning on swapping the CH

philmeister4 · 07-25-2020, 12:20 PM

Do you update charge pipes, j-pipe with a GTS Tune? What about at Stage 1?

M2C AW · 07-25-2020, 05:48 PM

Anyone have any idea what rwhp difference between stg 0 CS, and stg 0 GTS ?

Wondering why only 40hp gain when BMW said the GTS has 493hp. Stock S55 is 425hp right, so where are the missing horses? Water injection and increases boost, but that's a 30hp difference? What am I missing?

chewbakam4 · 04-07-2022, 06:20 AM

493 is crank power not at the wheels from BMW

theweebabySeamus · 11-30-2022, 05:06 PM

I flashed the GTS tune for the first time and I was surprised to immediately notice a difference driving around. Makes more sense now.

spidy512 · 11-30-2022, 10:46 PM

I echo this.

It took me some time but when I finally flashed to the GTS map, I was so stoked with the increase. The drivability was what improved the most for me. Combine that with the GTS tranny/diff flash and I am a happy camper.

I am holding off on stage 1...for now...

I really appreciate this post. Right what I wanted as I'm exploring tunes without replacing the crankhub (for now)!

Did you ever go stage 1?

I've been running the CS+ tune with no issues for 2 years now and am very happy with just that. I have the option to do stage 1 but I'm content with stage 0

Thanks for your feedback! Do you know the difference between GTS and CS+ tune?

I've tried looking for stage 0 tune comparisons without success. Would be really intresting to see the differences GTS, CS, CS+! If you have any more information please send it my way

That thread shows the BM3 CS vs CS+ tune, which doesn't exactly answer your question, but does show CS+ vs stock and you could extrapolate from there. I know different dyno and different conditions and all of that don't make it a purely accurate comparison.

I don't think the CS+ vs GTS are that different based on the results of the dyno charts when talking peak numbers. The GTS should feel more linear in nature where as the CS or CS+ maps have higher TQ down low (about 500 RPM sooner based on the graphs).

Fwrigley is right, not much difference between the two maps, maybe a small difference In torque. I had both on my car and just decided to go with the CS+ tune.
