Can't find this on the website or anywhere else, a lot more info on the stage 1 tuner but not as much on the cheaper sport performance tuner.
and is it worth it to get a resonator delete through Dinan vs. locally?
Thanks for any tips

Dinan sport, comparable to JB+ is a quick install for a a noticeable power increase.
JB4 offers much more. It is a stage 2 tune with a smoother power delivery and a ton of feautures.
If you plan on adding more mods in the future, JB4 is the clear winner.
If you are keeping your car stock, its a tough choice
