Been 2 days since I gave them stock tune, so I emailed them and asked when I'll be getting a tune. And they responded that they are understaffed and don't know when they'll get to me. Not what I wanted to hear...... :-(
I'm guessing the graph is for pure performance tunes. Which would mean the performance/tow tunes would make a little less. I'm guessing about 20hp less....?
Wow, that's a lot of gain on the 93 tune! I'll definitely be doing that tune, since we have PLENTY of 93 octane down in the south. Thanks Mike for the feedback.
Yeah, people underestimate the refinements in the 18. I was very shocked by how smooth the ride is. For a second I had to remind myself that it was not the Navigator.
