The only things you'll notice while towing in higher HP or DD tunes are an increase in EGT while accelerating at a decent pace (NOT trying to keep EGT low) and early shift points. Otherwise, nothing else is too different.

hey thanks for the replies. I was worried about EGTs getting too high but I guess I should only be worried around 1200+?
