Jb4 ordered

[V8 killa]

Hello, Does anyone have any input on the jb4 for when I receive and install this beast?

Input? It’s the best tuner out there! Make sure you gap your plugs to .022-.024

Thanks for responding,Do you know by chance what they come stock? Or should I order new 1s? And do you know how beneficial a downpipe is or if I even need 1?

Stock plug gap is around .036-.038. It is pretty bad if you are running a tune.
