So would JB+ be better value than a JB4 if you want a quick, relatively mild tune? (No downpipes, intercoolers ect ect, no tracking, no racing. Everyday driving with a enthusiasm and just go stock with a piggyback)

If so, this is one heck of a 200$ well spent. Would anyone who had a JB4 or thought about JB4 OR has a JB+ share their thoughts?
