Scott, glad to see you are happy with your newest upgrade.
all of what he said is true, I have step 4's and they CAN smoke a little under low boost as well.
as for the towing issue, I was taken aback a few weeks ago, when i finnally got the chance to tow my little tractor (6000lbs).
it didnt do too bad on the EGT's, maybe 50F hotter on take-off. it was smouldering hot out that weekend too(90+F). but it did have a constant stream of smoke out the back, rather than just during low boost. now, keep in mind i didnt pull any hard, long, grades with it in tow so the EGT's could be a problem if you really had to work it up a long grade with 10-15000lbs behind it. mine stayed under 1150F with some moderate to hard trips up through the gears.
I am planning a trip to pick up a load of wood next week with mine. i hope i can make it back up some of those hills without having to get out of it. where im going has some whopers on the way back.
I'll keep you all posted.
if your the leader, the view never changes, all the rest are just sucking huge clouds of black soot
