SCT is on the way, what tunes should I get?

[Dan"gerous"]

I just got off the phone with vivian and ordered my sct. What tunes do you all recommend? I live up here in Michigan (not concerned about cold starting, I'll plug her in). In the summer I'll occaisionally tow a 5000 lb travel trailer and in the winter I may tow a 2 -place snowmobile trailer at about 3,500 lbs. Performance would be nice when not towing but I need to be careful. I'm the idiot that recently had head gaskets replaced with stock Ford gaskets and bolts
I would really like better economy both for everyday and towing situations.

get economy tow and looney. u have to get looney

The economy tune is a waste of time. I have one but will never use it. I have Innovatives Tow Aggressive w/Turbo Brake, Street, Xtreme Street and Xtreme Race. I was running the Xtreme Street daily but recently switched to the Tow tune to experiment.

As far as towing, the light loads that you will see won't limit your tuning much. Eric says that the Street tune that I have is good for at least 6,000 lbs. I have towed approx 4500 lbs with it and saw no higher EGTs than normal. I plan to experiment with that tune and the 8,000 lb camper. I have towed as much as 16,500 lbs with the tow tune. Max EGT that I saw on some hard pulls was never over 1050 and the tranny temp stayed below 185 all on a 90 degree day.

I can't really equate Dj's tunes to what I have because I haven't run their tunes yet. Cal Vivian and tell what you are looking to do and she will have good advice for you. I know DJ doesn't like to see heavy towing with his tunes, but at 5,000 lbs and under you should be good. As far as fuel economy, the Looney should net you as good or better than any of the other tunes. The trick is to be able to drive the truck in a fashion conducive to good fuel economy!

Matt, I was hoping the looney would offer good economy. That is the tune I would like to keep on it so that when I wanted the power I could simply push the peddle a little farther down. Then tread lightly when I wanted better fuel economy like hwy driving.

That's basically what I do with the xtreme street. If you have good gauges and good common sense, I don't see why you couldn't tow your 5,000 load with the Looney. God gave you a right foot to keep your engine safe!

[Dan"gerous"]

I won't have the gauges till Christmas (wife was looking for a present for me so I provided a summit catalog with the page marked and item circled ) I won't be towing anything until Jan-Feb when I pull my sleds.

no gauges???? be careful, the looney gets hot fast!!! but it is such a rush!!

[Dan"gerous"]

Is a diesel like gas where the colder it gets the leaner it gets?

[720Deere]

Colder ambient temps will promote cooler EGTs. The lower the intake air temp, the lower the EGT. It's not a fully proportional thing, but it does affect the exhaust temp.

Unless forced into an over fueled situation, diesel engines always run lean.

Usually the hotter tunes will get you the better milage if you can keep your foot out of it.
