Towing in higher tunes?

I'm leaving in a couple days, towing about 6000 lbs. I haven't towed with this truck yet.

7.3/ZF6, Stock injectors, stock everything except intake and exhaust.

The tunes between my Econ and "Street" I don't like. I don;t use them, and won't get them again on a reburn. However, I don;t have time to get them reburned.

How likely will it be okay in the higher tunes (Street) towing up the passes? Econ does great unloaded, fell on it's face with a load of firewood. No problem with EGTs with that. So I want to use Street if I can. I can use Daily, but it has a lag and is too smoky. The tow tune is terribly low on response and power, so I can't use that.

it will drive just fine, just watch egts.

fwiw my 60hp tow tune from php rocks.
the shifting is rock solid and its almost as powerful as 80hp daily driver.
i can get 30 psi of boost on 60 tow and egts are so friggin low.

If your dd tune smokes a lot, and your tow tune feels like crud, I can't give you an honest guesstimation of how well it will perform with your other tunes. But, if you have gauges and can monitor your EOT, EGT, and TFT, then I think you'll be fine. Don't let any of those temps get stupid and you shouldn't have a problem. I know people that tow 14K on a 140 tune; regularly, and without issue. Drive like you're towing something, and pay attention to temps.

Sounds good. The "Street" tune is similar to a 120 tune from DP I would say. I'm hoping I can stay in that tune the whole trip (1100 miles with three passes to go over).

However, it won't be too big of deal to move into DD when climbing if it runs too hot. It's just smokey taking off at lower RPMs. I can use it as my "smoke tune".

When I get back I'm going to spend the money on a Hydra and have a tune made right in between the Econ and Street, and ditch everything else. Don't need 6 tunes with a 6speed....

With the 6 speed you should have no problem keeping EGT's down. I missed that in your first post. I have an auto and like the choice of tunes, but with a manual I probably wouldn't as much.

High idle and whisper are nice though. I would likely leave it in a 120 position most of the time as well. I already do with my auto.
