Tow question

[Johnboy0972]

Ok guys next week me and my friends are going camping in the mountains in Arkansas. Albert Pike. Its southwest of Little Rock. Anyway I havent really pulled much with my truck. I will be pulling a 20ft lowboy loaded with firewood and 2-3 4wheelers. The bed of my truck will also be loaded. I have an 05 cc with 35's. Im running an SCT livewire and its straight piped. My question is which tune do I need to run? I dont have any custom tunes so it will have to be one of the canned tunes. Also should I run the jake brake setting? BTW there are 2 jake brake settings. What is the difference in the 2?

Thanks John

do you have gauges? if so then as long as you keep a close eye on temps then you can run what ever tune you want. but if you feel more comfortable then probably be best to run a tow tune. not sure on the 2 jake brake tunes. but i'm sure some one will chime in on it

no i wouldn't suggest running "any" tune you want. cylinder pressure is much more critical than egt or anything else and no shop is selling real time cylinder pressure gauges. egt may melt things, but egt can be fine and still have cyl pressure to lift the heads.

i would run a tow tune not having gauges and you should be ok.

O well I haven't heard that before I'm sorry I'm still learning diesels but that makes sense

Thanks for the replies. The only gauges I have are what the Livewire shows. I have the EGT probe kit but havent installed it yet. I figured I would probably try the 65 horse tow tune. I am still wondering why it shows 2 Jake Brake settings on there. Also I saw on a different post a guy was talking about the different things he was monitoring with his livewire. One was EOT. Mine doesnt give me that option. Any ideas?

Keep an eye on your trans temp and run a lower setting tow tune. My tow tune from IDP is only 310/560, but that's suggested for towing up to the limit of the truck. With 35s and stock gearing (I'm guessing you still have stock gears), your trans is working a little harder.

Sounds like a good weekend, have fun.

Your tow tune is 15hp less than stock?

Xtreme Street- 420-430rwhp/730-760rwtq- Not recommended for towing.
Street- 400rwhp/670rwtq- Tow up to 10k lbs.
Tow- 310rwhp/560rwtq- Towing over 10k lbs up to the maximum of the truck.

These numbers were taken from an email from Eric @ IDP.

All the tunes listed are measured at the rear wheels. I don't remember if the stock measurements are based at the flywheel or rear wheels, but I doubt that a stock truck puts 325 hp on the dyno rollers.

Im really not sure about the gearing on my truck. I havent done anything to it, but I dont if the previous owner may have changed them out. I had to make a trip out to Dallas this morn. Driving on the interstate at 70mph I am turning right at 2000rpm's.
