I run mine on extreme all the time with no problems! Just don't have it to the floor for a long time ( like past a quarter mile distance). Hope this helps!!

you can run that vehicle in extreme with no problems, I don't recommend towing anything in that tune.

I towed a 18' boat with it and temperatures didn't get over 850 degrees. I also did a full out run from a rolling start of probably 1 mile and temps didn't get over 1400 degrees.

I ran it for a month or so without monitoring. You shouldn't have to worrry about temps. It doesn't run too hot.

I ran my RCD 485 for 3 months with towing the same boat and never monitor temps either.

Part of it is because my Livewire is a piece of crap that cuts in and out constantly from day 1 and spends more time with a blank screen than with one that actually tells me whats going on. No one from SCT will answer my emails or my online requests or aparently my pm's here so that I can send it off and get it fixed without having to pay it out of my own pocket.

Matt, perhaps you can help?

so you are saying you never monitor temperatures because you dont have gauges but you know you never get over 850 while towing and putting it down WOT for at least a mile you didnt get over 1400?

We don't recommend towing in that tune mode. Also what is the serial number on the back of that device? If you run into any problems with anything send me a PM.

Thats right. I know the temps though because with the 1 mile run it was my first time monitoring and that was the first time that I discovered that the monitor cuts in and out. I was showing my buddy with his spartan what the SCT was capable of doing and he couldn't believe that I didn't even hit 1400 at WOT for as long as we did the run.

Then 2 weeks later i hooked it up to tow the boat. First time so I wanted to make sure that climbing the valley hill I would not run to hot of temps. It cut in and out again and has a high pitch squeal, but I managed to see that while pulling flat I only hit 700-750 and oh the hill I maybe hit 900 max.

and then I threw the tuner back into the glove box.

[03f250stroke]

right, so then you have gauges is what i was asking?

but you are also talking about a 6.4 with an sct?

Only gages i have are the factory ones in the dash and then the sct for monitoring...but it only works once in a while.

All the info condensed, no problem running in extreme. I just don't suggest towing over 10,000lbs without bumping down to the next level.
