Any b58 people running the new jb4 map? Wondering how much of a difference it feels compared to map 1. Gonna be pulling the trigger on the combo from Mike at x-ph here shortly.

Map 2 will give you more power and a smoother delivery .. We heard some really good reviews from our customers on this map

If your combo includes the VM downpipe, its about to run out of stock
