Smile jb3

If money is not an issue just get the JB3 . A used one here is about 425 dollar range. Yes it is easy to install the jb+ but if you turn the boost past default settings it may throw a code? The JB3 has different maps available so far I have tried up to map 5 and checked with bt scanner and no codes. I think if you keep your car close to stock and just use jb3 on lower maps it should be ok . The first time install took me like an hour. then I uninstalled it to compare the gas mileage after 2 weeks. then the second install took 25 minutes.
