I can't use the 100 hp tune if I want the extra power now and again for this version and the last. There is a hesitation when I try to get on it and I had to pull over the other day, because it was to bad to keep driving home. I just wanted one that was above the now 60 hp economy tune from versions ...

How long does it take to get a custom tune?

Mike
I sent you a PM and an email with a what the truck has as a factory tune in order to get a custom tune, just wondering if you received it. I tried the 100 hp setting from the r03 and it didn't seem as smooth as the 65 hp tune vr03. I realize that the 03 6.0L is trickier to tune then the later ...

I noticed that with the current update, it says the economy tune is 60 hp. When I first received my tuner (r03), it still had the 65 hp tune setting. Did anything change? I noticed the website that there was a test between other tuners for the 6.4L ford showing the comparisons. The only tune that ...

I just tried the performance tune and was having the truck surging/sputtering so I pulled over to put it back into the 60hp tune. Is there a way to get the 85hp tune as was mentioned above? The tune that had the most performance was the 100hp version r03. My info is VXAP2N2 and SN d009dd4

Ok, I understand,

I have the same problem with the jerking when I turn off the cruise control with my U7165. I finally tried the 100hp tune the other day and didn't notice anything different. I usually keep it on the economy tune. I thought about reinstalling update r03 that originally came with my tuner, since I ...

The fuel filters are fine.

When I use the cruise control with any tune installed, it jerks when I turn off the cruise control. When I have stock installed, it responds normally. Is the turner causing and damage? I just recently had my truck at the dealership, because injectors 2 & 4 were bad, but luckily I had stock installed ...

I also have a 2003 F250 6.0 and when I installed the 9r04 version, I get the same sputtering on the performance setting. When I first purchased my tuner in May 2008, I saw the most noticeable difference. But now that I have updated it twice to the latest version. I don't see or feel the performance ...

On the 65hp tune, is the limitations of the 8000 lbs on the towing weight or the GCW?

I get about 13-15mpg on the 65hp tune, 14-18 mpg on the tow tune, and 20 on the 100hp tune in the city. I take it easy in the city since I didn't live that far from work. Went on a little trip thru the mountains and got 20 mpg on the 65hp tune doing from 75-80 mph. Now that I am towing my trailer ...

I was getting around 15 mpg on the 65hp, 18 on the towing, and 20 on the 100hp in the city. Just recently went on a little trip thru the mountains and got 20 mpg on the 65hp setting doing about 80 mph. I have an 2003 F250 2wd 6.0 with 21000 miles on it. Just recently installed a 4"turbo back exhaust ...

I just purchased my first diesel (2003 F250 with 21000 miles) I have been using the u7165 for about a month now and noticed about the same in mpg. For some reason I would get better mpg on tow tune for city driving. I would got around 20 mpg. On ther performance setting, I got 20 mpg also, but ...

I recently was pulling my travel trailer (8000 lbs), and used the tow tune. When I reprogrammed the truck using the 65hp tune, the truck was bucking when I going about 65 mph. After pulling over and shutting off the truck for about 5 minutes. It was fine. I get better mpg in the city using the ...
