How to use the TW chip.

How to use the TW chip.
I got the chip working and I have some questions:
I choose 6 pos: stock, economy, heavy tow, street, race and high idle.
My questions are: when Im towing my TT, I always has to use the Tow setting on hills or flats, or I can use economy in flat ? this is because I want to get the best MPG and lower EGTs.
The other question: reading at the DP tunner page they said that you can Tow heavier loads with light Tow, than with Heavy Tow, Im confused about that, what do you think?
Thanks to all.

Jose you can tow in what ever program you want as long as temps are where they need to be. I wouldn't recommend towing in Econo simple due to the earlier shift points. I towed a 24 foot enclosed car trailer loaded in street race with no issues at all other than kicking OD off to keep temps in check.

Thanks a lot guys. I cant wait to tow with the chip in.

I base my chip setting choice on my EGT, if my load is too heavy for a particular setting, I turn it down a notch. Now that I have added the IC, I don't need to use the heavy tow anymore.

I think you have that backwards. I have both heavy and light tow settings on my TW chip. The heavy tow has nowhere near the power of my light tow setting, that's why it's better for heavy loads, less fuel.

My light tow doesn't blow as much smoke and therefore has less power. My heavy tow has more power to pull the heavier load.
If the load gets too hot in the heavy tow I would switch to the light tow because of less fuel and heat but also less power.
Kind of sounds funny or almost backwards but that is how Tony lists them on his burn list.

That's what I understood on the Heavy Tow as well. I like the way it runs with a heavy load and don't regret not getting light tow to find out. I don't think I've had it on any other setting for normal driving, just like the torque feeling.
I haven't ran extreem enuf to know how it does, biggest thing I've noticed is in lower gears it revs almost too quickly.

I'm not arguing, but I still think that light tow is more fuel and power than heavy. You can't throw more fuel at a heavier load for long, if that worked, everyone would tow 20K lbs. in their "extreme" or "race" tune. My tunes are in order of increasing power/fuel, stock, high idle, heavy tow, light tow, daily driver, and stupid. There is a very distinct difference between the two tow tunes, heavy isn't a lot more powerful than stock, and light isn't much weaker than my daily driver. To me that makes sense. If I'm pulling a light trailer, I ought to be able to manage EGT with almost as much fuel as I'd use running around empty. I'm done now.

Thank to all of you.

This is from Tony's site.
So it sounds to me like heavy tow will produce more power and higher EGT's which could be a problem when pulling a heavy load without an intercooler.
Oh yeah, he doesn't list a light tow option...
Just tow and heavy tow.
- Tow is going to be approximately 50hp increase for the 94-97 models and 65ish for 99-03 models.
- Heavy tow will have shift points adjusted and an increase in power over the regular tow program.
