Just bought the evolution CTS3 tuner but after updating the software and hooking it up to my truck, there is no “towing” tune. Any suggestions on what pre programmed tune to use for towing purposes? Tunes listed are: Driver, Performance (requires 91 or higher octane), extreme (93 octane), and various tunes for different octane and CAI configurations. Thought about trying the K&N CAI w/ 87 octane tune but wasn’t sure since I have a Spectre CAI. Thanks in advance, this is all new to me!
