I have put about 2,500 miles on the truck as of the
tune and here’s my update.
Unfortunately, moving from the OVTune 2.0 tune to this one was a pretty significant downgrade for my use case and I need to flash back to OVTune when I can (but I don’t have my original file anymore).
The Valley Tune does pack more of a punch when you tap the gas. It feels like it might be fun for mobbing through the desert at 10-30 mph. If that’s what you’re looking for, you’d probably enjoy it.
That wasn’t what I
needed though. I was looking for a tune that cruises well at highway speeds and might have better mpg than the OVTune I was using (not because I expect decent mpg with my truck, but spending less time stopping for gas is nice).
Comparing the numbers, the OVTune was better for me— someone living on the road while traveling the country:
OVTune 2.0 city mpg: 11-13.5
OVTune 2.0 highway mpg: 13-15.4
Valley Tune city mpg: 10-11
Valley Tune highway mpg: 8.5-10.3
OVTune 2.0 RPM at 65-80 mph: 2,000-2,500
Valley Tune RPM at 65-80 mph: 4,000 almost constantly
OVTune 2.0 gear hunting compared to stock: Great
Valley Tune gear hunting compared to stock: Poor (similar to stock)
This feedback is based on a very
heavy truck (still need to weigh it), 5.29 gears, 37” tires. My truck isn’t meant to have nice numbers to begin with but the tunes are relative and the differences feel huge.
