You are scaring me with the warranty concerns. My 2019 has 6 more years of bumper to bumper warranty. Don't want to jeopardize that.JB4 is a neat tool for someone who doesn’t want to reflash the ecu. There’s no guarantee that your warranty won’t get voided due to traces it leaves behind (both physically in the form of the wiretap at the O2 sensor wire and the rubber grommet at the firewall being perforated and digitally in the form of logs at the ecu if a deep investigation is performed), but it’s user friendly, relatively easy to install and the end user support from George is top notch. I was amazed as to what it could do and how the user input map is adjusted over data logging and email correspondence.
For me, it’s easy to go from Map 0 (factory) or Map 1 (roughly +4psi} for a track day, Then Map 2 (roughly +5psi) or Mao 6 (scalable up to +7.9psi) for daily driving/ around town fun! All controlled from my iPhone.

Can VW service see the boost was increased from some external controller like jb1?If you want a mild performance increase with no physical trace, then go with a Neuspeed Power Module on +5 or a JB1! Plug n play at 2 sensors and you’re done! Removal for warranty/service is easy.
That’s a little paranoid... the hole in the grommet could be anything... that where my power wire is run through for my stereo system, and the O2 tap fears could be dealt with by changing the O2 as you tap on the hardware side of the connector and not the engine harness.

also they sell a splitter on eBay so no wiretap is needed

I wasn’t say the OP was paranoid, I was saying your post was, haha.I tried using that EBay loom. You can have mine- it throws a code.
As for the stereo or boost gauge lines running through the grommet, that’s fine if you actually have stereo equipment or a boost gauge!
I wouldn’t say the OP is being paranoid- I went through the same thought process of what to get/ how to be as stealthy about it as much as possible last Fall when I got the ‘19 GTi. I tried NPM at first- it was ridiculously easy to install and use and a no brainer to remove for service.
I ended up going JB4 for being able to switch through the maps for track days, knowing I could still take it all out in a pinch for major warranty service- yet knowing it does leave those minor traces that it was there- something a knowledgeable service tech could look for. Both the pinhole in the wire and the pierced grommet could be replaced but there’s added steps there that the OP should be aware of before making his decision.
