Custom tune issues?
I started my own post so I wouldn't hijack the other gentleman's post with the same problem.
I've been running the canned level 2 since I received the Gryphon. On my truck this wasn't near the improvement over stock others mention though there was a slight improvement. This made me quite anxious to get my custom tune in hope there was more performance to come.
I received my custom 87 performance tune 9/30.
I drove it 85 miles thinking to myself something aint right here. The new tune feels like stock performance with perfect shifting. I programed it to the level 2 canned tune, canned level 2 is more powerful feeling with so so shifting.
I tried stock VS the new custom 87 tune, there appears to be no difference in performance though the shifting is night and day better using the custom tune. I re installed the custom tune due to the vast improvement in shifting. So far 140+ miles on the custom tune.
I am quite disappointed with the custom tune.
Hopefully there is a remedy.
Level 1 custom 87 perf.
Level 2 canned tow.
Level 3 canned 93 perf.
