Its a really nice linear mapping and we think its perfect for road course duty. Our local beta car here (@farbmw) has been to the Canadian Motorsports Park and both him and instructors had great things to say about the tune that was on the car at that time. It was putting down quite a bit less torque than our last Stage 1 revision which we're referring to a street map. Its quite a bit more torquey and great for street duty/fun.

ProTUNING Freaks, I know this post was from a while ago, but do you have a more road course friendly OTS Stage 1 vs. a street/fun Stage 1?

If so, can you post dyno charts of both track and street OTS Stage 1 maps? I was not able see anything on your site or this forum... thanks.

Forgot to add a legend, I figured people would expect more power from stock to St 1 to stage 2.

Yellow: stock
Green: Stage 1
Red: Stage 2

It's meant for stock hardware no issues, customers have been running it for the 1-2 year with Free Updates to the maps

Hey guys is it possible to change stock settings to comfort, comfort and efficient.?

Is it possible to go stage 2 with High Flow Catted downpipes?

You can run Stage 2 even on stock downpipes. They’re not required just recommended.

Brother ran Stage 2 on his X5M. 36k miles. 5k miles into Stage 2, cats needed replacing. Put two and two together, but thanks for your take!

Haven't heard of this, but S55 primary cats are very different than V8's cats (more restriction).

I acquired my f80 with the stage 1 ACN91 (Beta) tune....is there a benefit to switching to the stage 1 ACN91 (non-beta) flash?

Maybe the issue here is back pressure of turbos? OE cats won't flow enough => too much back pressure => bad for your turbos🤔

If you go too heavy on burbles and pops you can cook your converters from the combustion inside your DPs. This is why the AGG maps recommend catless DPs. If you turn off overrun/burbles then Stage 2 works fine on sport cats or OEM.
