Care to explain jb3 vs jb4

[WhiteTgr135i]

Sure, the major difference between jb3 vs jb4 is the extra features the jb4 has, such as turning the gas gauge into a boost gauge, the turn signals into shift lights, and jb4 having able to change maps, as jb3 only has 1 map i believe and doesn't have those extra features. The jb3 vs jb4 power difference is only 10hp and 10-15tq. So unless you want those extra features, stick with the jb4, but if u don't care about the features, the jb3 is more then suitable. Also, if you buy my jb3, and later down the road want to upgrade to a jb4, you can send your jb3 to Mike from n54tuning.com and upgrade to a jb4 for only 150$, saving some money.

Yes, you are correct.
