Not much info out on the forums with any details. 190/50s and stage 1 turbo.
I towed my boat about 240 miles yesterday at 60 mph and part way into the pull I decided to change tunes to see if I could improve fuel economy. So about every 50-60 miles this is what I saw. I didn't have a tow tune available, but it was interesting to see what the results were with what I had available. The transmission shift points were fine, except the T/C locking in 6th was a bit too low on the Extreme for some of the hills. Smoke was pretty much non-existent.
The boat and trailer are about 6,000 lbs (23' wakeboat).
Aggressive Street (worst economy. However, this tune has the best economy running empty.)
Mild Street (about 2-3 mpg better than worst)
Stock (warmest temps. About same fuel consumption as Mild)
TDP Extreme (Great EGT and power. Economy slightly lower than Stock)
