Also would add here that I am in Texas, with Map 2 I have been running it has been around 100*F consistently and the power gain is noticeable - echo this maybe you have a faulty unit? How long has it been installed (perhaps for ECU adaptation)?
Just a guess here. I would check the MAF sensor connection both at the MAF sensor and at the connection to the JB4 - Clear the code, and see if it re-appears. I would defer to the Burger boys on if that's what you should do, but that's what I would do!
For science, data re ran with the accurate weight of my car:

Emira V6...
Alright, so after a way longer than I'd like to admit fight with getting the sensor clips to release (don''t want to break them!), I successfully installed the JB4 this morning. I have a bracket coming so I actually just ran the actual unit in the trunk with the wire sitting on top of the trunk...
Stoked for a ship notification - but won’t hit my hands until Monday. Guess I will have to wait another week to start the party (or if I have a evening this week to get it in)!
I’m looking forward to my wife possibly thinking the Emira is “fast” now (Taycan GTS daily).. 💩
Thanks for the feedback; Personally, I was hoping that was the answer and would assume with "cleaner" A/F ratios it would not burble as much - I enjoy it sometimes but most of the time crawling out of the neighborhood the low RPM 1-2 shift tends to backfire loudly!
Can anyone answer if this increases or reduces the "burbles" that the factory tune has? I think it's actually quite rowdy (especially with TI exhaust and 3rd cat delete), so I'm curious if this increases, decreases, or remains roughly the same - @mr.suntorytime any feedback with the testing here?
Checking in - the dealer finally did an alignment after I made a stink. Completely resolved all of the issues 100% - I think it was partly that it was one of the first they delivered and they didn't even have the alignment specs at the dealer from Lotus yet - They tried to improve it without the...
