BM3 Stage 2 60-130 runs
Pretty disappointed with these numbers, although I’m on the bm3 OTS stage 2 91 ACN I really expected more, unless somethings wrong with my car
I did 3 consistent runs and got the same times, exactly the same which means it’s consistent Granted it is pretty humid outside around 80% per the weather app, I still didn’t expect these numbers, curious to see what y’all think. Current setup is Stage 2 91 ACN OTS BM3 Downpipes Intakes |

I think you’re right, something is iffy here. Stock on 91 should be around 8.5s. On 93 it should be around 8.3-8.4. Stage 2 BM3 93 is about 7s.
These are numbers that I’ve seen from other members and Instagram over the years, not mine. |

I’m trying to figure it out, I’m assuming it’s just insanely humid

The ACN tunes are really slow compared to the 91 and 93 tunes. They only run in the 6-8 degree of timing range while targeting just under 22 psi of boost. The standard 91 octane tunes are up in the 12-13 degree range. I found the stage 1 91 faster than the stage 2 91ACN. I’d do some data logs to confirm it’s not pulling a bunch or timing and to confirm it’s hitting boost targets.

At this point I think my choices would be maybe to supplement meth into the mix, therefore I can run a more aggresive tune. The issue with the data log is I’m not sure what to compare it to, no one really runs this specific ots tune |

I’ve ran it a little while too and it was definitely slower than when I was running just the normal stage 1 91 ots map I’m running the stage 2 91 map now and it seems to be fine. I’ve even tried the stage 2 93 map and just mixed in a little e85 and it felt a lot spicier then but a little worried about fuckin the car up on that map I live in NorCal.

I’d be willing to risk it but I just don’t trust running it like that for a while incase you run into one really bad knock. Mixing e85 is what I’m looking into but I don’t wanna max my trims then run lean |
