I tried the 91 tune today, it failed and said it went to recovery mode with an error E-55 and to call Superchips. I disconnected it and then plugged it back in. The unit then reverted to the stock settings. So, with trembling hands I tried again. It finished the procedure and said the 91 tune was installed. Jeep definitely feels better than before.
I wish the manual had a little more detail than just giving general descriptions of what can be changed.
I'm leaving it at the 91 tune for now. Soon I will be going to 35's and 4:88's and will adjust for those changes, hopefully with no problems.
