Now thats more like it!!! Much better throttle response than (14a), low to mid and great passing response, seems to be nice and smooth across the throttle range, no hickups or dead spots or surge. I have not traveled enough to get a good mileage report but will reply when I have some news. I have ...

MikeL and Buck,
Thanks for the reply and here's my original backup. Send me something wicked when you have a chance.

Agreed, nice tune especially when your foot is in it, no more codes that I have found either. I have been running 8r17 and although it surges it has better response in lower RPM's but not as much when you push it hard and not as much boost maybe 20 max on the factory gage, the new tune hits 30 ...

What are your thoughts about the newest tunes from ford as related to power? I have been thinking about taking it in and getting it updated to prevent FICM damage due to the inductive heating method in use with VXCF5H5. Also been considering getting the FICM programmed with a hybrid program that has ...

Hi Don,
I have VXCF5H5 and previously ran 9r07. When I loaded 9r10 I immediately noticed a significant difference in engine noise. 9r07 is much louder than 9r10 any reason it migh be? Also any idea as to power difference between the two, I never saw a dyno graph of 9r07?

Cole, I would like to try an r20-100 custom tune something closer to r17-100 if one's available. Currently I'm not getting any codes or having issue with r20-100 other than what I've already stated.

Highway mileage feedback: Just got back from my weekend trip where mileage was 16.5mpg by the computer for r20-100. This was all interstate (less than 20 in town) with cruise set at 70mph, tire pressure set as usual and no load.

I prefer not to have the smoke usually that means more waste than performance gain. I have a white truck and trailer and want to keep them that way, enough washing as it is so no smoke for me. As noted, when I tow, I use the tow tune only. And if I loan a friend my truck I always return it to the ...

The dinner bell rang and in my haste I forgot to extend my thanks for your efforts!

I have had r20 100hp loaded for a couple days; unfortunately I have been local and have not traveled as much as I normally do.

Mileage: In town my mileage appears to have increased from ~12.5 to ~14.5 on a partial tank according to the dash readout. I may be out of town this weekend and will ...

I was getting 19.5 mpg running ultra low sulphur with base file VXCF4H2 and r17. Took the truck in for another problem and it came out with VXCF5H5, looking back wish I would have never taken it in. Now with r19 I’m getting 14.5 mpg at best with less power. As I understand it, Ford changed the ...

MikeW,

Is it correct to say Ford is the only one capable of changing the base file once its in a vehicle even though I may have a backup of it on my PC?. The reason I ask is I want to prevent being stuck without a DS tune until its supported. I went 4-5 weeks without a tune due to the last base ...

MikeW,

What is the reason behind the idea of developing tunes for each update Ford releases? If you are doing this and reverse engineering the code each time I’m beginning to understand your quandary. Since the debut of the 6.0, how many of Ford’s updates really address issues that would ...

Cal ID is VXCF5H5, Serial 2000693, Part U7165pcm_6_0, 100HP tune.
4-6 mpg drop in fuel mileage, strong diesel odor at idle (not there with stock tune), not as much power and fun as it used to be. Truck has a 4" MBRP exhaust, cat removed, AFE Pro-Guard7 cold air intake system and Accufab elbow. I ...

I guess sometimes silence is bliss... but not in this case. I would love to hear form someone in a prominent position at DS instead of the usual tech's with open ended promises...
