Another positive vote for the JB4. I've had it on the car since it had 7,000 miles, and not a single hiccup. I daily drive it on one map, and fill up with higher octane and have fun with faster settings when I feel like it. I've taken the car to the track, never any issues. The support from George is second to none. Also, your mileage may vary, but my dealer is very mod friendly so as long as I unplug the OBD connector from the port when I take it in so they can do their work, they don't even care if I leave it on. I've had warranty work done since they've seen it, never even a question about it.

Just in case anyone is interested, I listed the JB4 in the FS section.

What map do you recommend? My car is a stock B9 A4 (254hp). Connected the app this evening and it’s saying Map 5. Being a noob I can’t remember if that’s what I had it set too. Running 91 oct. Thanks in advance

91 = map 1. Don’t drive the car on map 5 with 91 octane. Which firmware is it?
