Towing was why I stopped using the GH tune. I really didn't like how the torque and shift schedules were aligned. I was CONSTANTLY having to intervene.I for one recently switched back from my 5* dedicated 91 tune (3-4 revisions) to the latest GH AO Tune.
Honestly, I like matts (GH) tune way better for drive-ability,,,, it is very stock like normal driving but refined for the better, but as you command more, the more aggressive it gets and when you command WOT,it has great pull, really great!. The transmission operation is way better with matts vs 5*. So much smoother and crisper. I think the 5* dedicated 91 might be a tad faster.... but only the track will tell this.... With the 5* tune the Sport mode is more aggressive than Matts AO Performance, but in no way is that better.... (shifting firmness)
When I was conversing back and forth with matt recently, here is one of the quotes from our conversation when I asked him about the E15 mixture:
My Question- The manual says we can run up to E15...... Will your adaptive tunes adjust for the added octane if I stay at the E15 limit?
Reply- "E15 is fine with the auto octane. It will give gains up to about 94 octane"
I for one am very happy with the AO tunes and the ability to live safely through a bad gas experience and/or when traveling not worry about where i need to look for specific gas.
I agree that it was fantastic for daily driving.
