problem is 6.0l's are a lot louder in cold ambient temps (-20), vs warmer temps even when stock.
Now a tuned 6.0l is noticeably louder then a stock tuned 6.0l in the first place, thus my concern.
I also wonder why the tune has to be louder at idle in the first place, i suppose it could be to lessen fuel usage by advancing timing, etc when idling, but does it have to be that way?
My concern is not really the diesel " noise ", its hard to explain, but if one has ever heard a cold and i mean -30 c cold 6.0l, run then they would know why i might be concerned about tuning on a 6.0l at -30c.
Of course common sense applies to allowing any engine to warm up before driving but my concern is the initial start up.
I guess what im wondering is that on a stock tune vs custom tune is extreme ambient temps taken into consideration?
