I know I see a fuel savings running 55MPH over 65MPH... 60 is a sweet spot, but this is based off my TDI.
We haven't had the Libby long enough to compare.
The principals are the same, so it sound see a boost in economy.
I think the CRD's spot is 62 when the it reaches the final shift point. You can then slide back to 60 before it shifts back down though. These are post F37 figures

That's the only thing I like about the F37 flash. My 06 shifted earlier for the first 2 weeks I owned it and droaned at lower speeds. (I secertly got the F37 flash when I took it in for a coolant leak and they flashed the BCM for running down the battery) Later when they gave me the F31 I got a different F37 and now it revs to 4 k when the little peddle is down before it shifts, that Part I don't like

I drove my 99.5 (A4) jetta between 65 and 70 MPH as a rule and I once got two tanks in a row that were a tad over 70 MPG

But everything was right and the plannets were aligned

Around here the fuel is crap and that hurts mpg's a lot

62? I noticed it was running as close to 2k/rpm as it could, and I figure it hasn't hit final drive. We have the F37 recall performed, they replaced the TC in it... I'll try 62 this afternoon and see if it drops down to the 1k/rpm range .... thanks for the tip!
