Here's a clip of some 91 burbles. The clips were taken when Alex was refining his 91 burble tune so burbles now have significantly improved. I was able to find some 101 octane near me so I had Alex send me a 94 map with burbles and they are way louder and more consistent at 94. 91 is just terrible fuel.
They also take a bit of practice to get down perfectly, you let off around 5.5k rpms and slightly press the gas pedal in to control the burbles. I wasn't really used to it yet in the video but I've perfected it now, makes for some sweet tunnel music
As for power gains, on 91 I did feel a nice jump in upper rpm power. Was really surprised at just how noticeable it was, for the record I am completely straight piped with an RPi GTM race exhaust. I was really happy with my 91 tune.
Then Alex asked me if I was able to get any higher octane fuel, as 91 is garbage and I wasn't unlocking the full potential of my M3. I stopped by Sunol Super Stop and filled up on 94 octane and filled a separate 14 gallon drum up with 101 octane to mix into my 91 later. Alex sent me my new 94 map and we installed it.
The gains, according to the butt dyno, are massive. I couldn't and still can't believe how much gains are felt. It feels like a completely new car, pulls extremely hard, especially after 5,500 RPM's.
You know that feeling you get when you first drive a fast car and it kind of scares you a bit? Same effect lol.
With this new tune I was able to walk away from a C63 AMG very convincingly.
I highly recommend Alex and his tune, I am going to try and get on a dyno soon but I am in the process of wrapping my car and have to get an alignment soon.
Here are some before and after numbers (93 is supposed to be 94)
