Non Comp 2018 You will get there. For your goals I would remove JB4 and sell it. A decent pump gas tune will hit your goals of set it and forget it with a 2.8 - 2.9 |

Thanks Your times are a good example of my Frustration. Here are my logs: Stock 3.20 DA 1077 (did right after or shortly after break in seduce and this time was hard to get. It was best of maybe 10 attempts over a few days) stock 3.24 DA -397 (negative 397) - I show this one because it was the next best time on a very cold day with very low DA in So Fla JB4 Map 1 - 3.05 DA 1805 I did this pretty consistently but again this waste best with most times above this but typically less than 3.2 JB4 Map 2 - 2.94 DA 790 Again this was best after many attempts in the low 3s This map was very inconsistent. Some where horrible north of 3.5 Everything else has been worse (sometimes much worse) probably have done 20+ LCs trying to consistently get under 3 Admittedly, I did one 2.90 sec on map 1 but it was invalid due to a negative 2.90% slope - DA 1454 |

Your stock times do seem slow though. I was able to get a 2.90 in my non comp and an 8.01 60-130 stock. Just about every launch I was at 3.00. I feel like some are just faster than others, not sure why. If you don't have Michelin Pilot Sport 4S tires they could help at least with the consistency. Other than that all I can think of is either you're not launching it right somehow or it's a dud. There have been a few people on here with the same issue, not sure if any of them ever figured it out or if they all just gave up.

But again this is why I'm so discouraged
I know we are are talking about 1 or 2 tenths here and there (and whether 3.1 or 2.8 the car is fast ... but it does seem slow ... I wish one of you could drive it and see what I'm talking about .. I mean maybe it's the humidity in Florida .. I dunno |

Did you read my post above, 0-60mph is a total crap shoot? Stock cars can run faster than tuned cars 0-60 because it's all about traction and how well launch mode decides to work that moment.
You are on the right path looking at 60-130 that is a much better measure to evaluate tuning performance. |

Looks good! Boost is smooth and in a safe range for 93 octane. Timing is much better. Still could go higher, but even these tunes take a week or so to adapt.

I will try to upload a little latter
Here is a log of the most recent custom Jb4 Map 3 / DME Combo Also, a dragy 60-130 (technically invalid because of < 1% slope) .. 7.89 for this same run .. I think it could be a little faster?. This is all on 93 pump. No other mods. I have cf roof and the standard breaks, FYI |

The logs are much better and the 60-130 time shows that. But it's still looking slow. 60-130 stock on a comp if I remember right is about 7.8-8.0, with a valid slope.

I agree. Still looks / feels a little slow
It was a first run less than 24 hours after flashing I'm going to give the car some time to adapt to the new mapping Might change FF to 40 from 30 on customs map 3 after a few days to see whether that helps too (per Mo) Also I bought 5 gallon of 100 octane so I'll mix some of that in a few days after car adapts today the tuning |

No you'd leave all the settings the same. Map1 and map2 are largely independent of the settings entered. Just something to try since you're recording runs anyway.
