This basically applies to any OTS tune. JB4 can be used reliably and safely, and you can tune it. I'm not going to lose mine when I finally get unlocked. It's a solid tool, user adjustable, on-the-fly map switches, etc. JB4 is just a tool. Use it right, and you won't grenade anything.Also you're more likely to grenade it on a Jb4 with OTS maps than are you are a pro tune where an actual turner is adjusting maps based on your specific car, altitude, mods, IAT, fuel grade, etc.
Warranty - yeah. Whatever. I'm happy to pay to play, unlike that dude with the amplifier.
