Phoenix questions
 

I am new to the world of diesels. I have an 01 sd ps with a 6spd. What is the difference with the tow tunes? I will do a lot of towing with the truck, about 9k-11k. What tunes should I get? Just want to make it the most driver friendly and need the truck live for a long time. The truck has 4" exhaust, ais intake and egt and boost gauges.

25 tow (heavy)
40 tow (moderiate)
65 tow (light)

First, let me applaud you for getting the 6 speed, I wish I had the foresight to do that when I got my truck. I just ordered a chip for my 2003 with 25 tow, 40 tow, 80 tow, 80 Daily Driver, and 100 performance. I really only wanted my chip to help with towing my 14,000lb 5th wheel, but I knew that once I saw what the chip could do I would wish I had a performance tune, so I went ahead and got one.

Thanks. But what is the difference between the 80 tow and 80 performance? I don't have have shift points to move. I don't want to have two tunes that do the same thing for me. I will also be doing a lot of driving with the motorcycles in the back so I need something that can help with mileage.

Well, I won't be able to answer those questions myself until I get the chip and install it. I'm sure there are others on here that can explain it though. Also, if you haven't already, check out this website:

1999 - 2003 7.3L Power Stroke Diesel - Ford Truck Enthusiasts Forums

Lots of good info there specific to 7.3L Fords.

Driving habits make more effect on mpgs than a chip.

In the world of "hand-shakers", the tune selection becomes a bit less creative because of the lack of transmission tuning. In the grand sense of things, getting an 80 HP Performance tune and an 80 HP Tow tune would not be a total waste on a M/T but it would certainly have a reduction in perceived difference.

In a nutshell, tuning goes like this:

• Tow - Moderately aggressive throttle curve, slight increase in low boost fueling
• Daily Driver - Conservative throttle curve, no change in low boost fueling
• Performance - Moderately aggressive throttle curve, moderate increase in low boost fueling
• Racing - Aggressive throttle curve, aggressive increase in low boost fueling
• Extreme - Aggressive throttle curve, maximum increase in low boost fueling

In general, few people will go with both an 80 HP Towing and 80 HP Performance or Daily Driver. We usually recommend to spread them out a bit to take advantage of the selectability of the switch.

I hope this helps answer your questions. :D

Bill, this makes me question having ordered the 80 Daily Driver and 80 Tow tunes on my Phoenix. Should I tell you now that I want to go with something else since you haven't sent me my chip yet?

Entirely up to you. It's not unusual to go with calibrations of the same HP rating, I just tend to prefer a bit of a spread myself. If you'd like to make some adjustments to your power levels, I'd certainly be happy to adjust your order. Just let me know what you decide.

Thanks.

It seems like I have read that the smoke tunes can be kind of weak unless you move up to big oil. Is that true? I think a smoke tune would be fun, but only if it really works.

Actually I'm kind of thinking now that I may just go ahead and get the 100 RAce tune. I want to do away with the 80 tow tune completely and add the 100 race tune to the final position on the chip. Do you need something more official than this?

Thanks

Could you use the 80 HP economy for towing light loads on a 6 speed manual? I want to to get one tune that i can get the best mileage with and still have some extra jam.(which i think would be the 80 hp economy)

I will be mostly hauling my Polaris RZR on the back of my truck and then pulling a trailer with a GVWR of 8600 lbs.

I was thinking of getting the 65 hp tow(for the trailer),80 hp economy, 100 hp performance and the 140 extreme(since i have forged rods).

Thoughts?

OK, I'm sorry for going round and round about this, but I think I just want to replace the 80Tow with 65Tow, in the same position, which should be position # 4. So my total rundown would be

Stock
25Tow
40Tow
65Tow
80Daily Driver
100Performance

I will send this to you as an email also.

Thanks

Got it, Bob. I'll get it over to Corey. :)

Thanks Bill, I got an email from Corey confirming the change.
