I have a 16 bMW M6 with Dinan tune, exhaust and airflow system. Never Dyno’d but supposed to be 693hp and 650ish tq if I remember right. It is significantly faster than when stock.
I have a 19 ram 2500 diesel I am thinking of getting a tune for that promises all kinds of great hp, tq and mpg increases. Can’t remember the brand but it’s only like $800. Anyone have an opinion?
