i dinan stage 2'd a 550 and after 3k miles it blew an ignition coil and had a cpl bad spark plugs and then started leaking a lil oil.. im sure 16s are better tho
by the way i am not saying anything about any tuners..
just the anonymous OTS maps.. that are anonymous to my knowledge
either way No one has called any names in their blown engine reports I'm just adding together bootmod3 and blown engine but running OTS maps has been stated
its really just tunes push the envelope... all of them .. but some more so than others.. just doing math
