Car seems to be underperforming after installing JB4

[HScorpion]

Hello all,
Not sure if there is a designated person that can help (either here in the forums or JB4 team) but i recently installed the JB4 to my '22 Stinger. The car seems to be running fine but when i logged the time, it seems to be underperforming. My current 0-60 is consistently around the 5.10's which is worse that stock numbers. The best launch ive had so far is sitting at 4.93 seconds on map 2... Is there anyone out here that can read these logs and help me make sense of what is happening? The provided logs are also short runs so I am not sure if there is enough information in them or if i should log the times for a longer period of time. Thanks in advance!

Current Mods:
AddW1 Blow off values
Air Intake Snorkels
BMS Intakes
Denso 5346 IKH24 "1 Step" High Performance Spark Plug (gapped at .22)
Borla Type S Exhaust
93 Octane
Tires: Continentals Extreme Contact
Lap3's Upgraded Coil Packs (im pretty sure these are just stock coil packs)

Are you using a draggy or similar and comparing to your times on map 0 and map 1?
Surface condition and driving style have a huge impact on 0-60 times. You'll get terrible times if the wheels are just spinning, which is definitely what will happen if you just mash the throttle. You can get worse times with more power, especially if traction control is disabled.
You should definitely feel a difference in the mid-range. For me, accelerating from 30 is the big "oh shit" experience. Getting a good launch is actually quite hard.

Yeah, I'd probably take launch out of it entirely if trying to see/confirm the power increase from a tune. The first column is a timestamp, so you can select a gear and get on the throttle from a roll (say 25mph in 3rd), then pick a start & end speed in your logs, subtract the timestamps, and repeat for other maps.

Yes i am using the draggy and I am making sure to do these logs on a nice dry sunny day since i am using launch control for these runs. I have AWD so i dont even spin on these launches. Maybe i am overthinking it but i cant tell if there is a power difference between Map 1, Map 2 or with the JB4 off. I guess my main confusion is why my car would be launching "slower" with the tune then a stock launch.

Interesting, i will have to try this out. Someone from the JB4 forum said that there is "a significant amount of timing being pulled". Not sure what that means so hopefully they can provide a bit more insight.

So what are your times in the same conditions using the same car settings on map 1 and map 0?

So Map 1 i ran a 5.20 sec (0-60) and Map 0 i ran a 5.60 (0-60)
I just logged a run in Map 2 - Sport - 2K RPM - in 3rd gear in case anyone can take a look and let me know if they notice anything (still tryna learn how to read logs)
Also follow up question, but has anyone experienced JB4 not logging runs? I did 2 other runs besides the one attached but after I got the "writing file" screen, there was no additional logs in the "logs" tab?
