I’ve put on about 30k miles now with the JB4 and it’s been great. The Bluetooth adapter is awesome for real-time monitoring and on-the-fly map switching. I’ve had to uninstall and reinstall it twice for 2 warranty work dealer visits unrelated the to the engine without issue. I run map 2 on 91 octane daily and bump up to map 5 with an E85 mix. I’ve got the JB4 tuned BMW for a ‘fast’ car, but the Raptor really MOVES with the JB4!I’m not affiliated with BMS in any way, but I’ve been running their tunes for 10+ years now on various platforms so I can honestly say they’re 100% legit.Nothing wrong with COBB or the other tunes I’m sure, but with everyone jumping on the COBB bandwagon right now I need to say this.... I’ve seen COBB come and go on other platforms, but BMS is STILL in the game and active with R&D. THAT should say something.</blockquote>
