ARH Longtubes. What tuning is required?

[Mark247]

Looking at getting a set of ARH long tubes for my 12 ram 1500 but have read on here custom tuning really makes them come alive. What exactly is done ? and without a tune what would I expect in terms of codes or power?

Thanks

as far as tuning a Diablo Sport with Hemifever customized tuning will highly recommended.
