You have to do it on the tuner unless you have CMR software, which you don't. It isn't that hard and is very fast with the InTune...I did all my adjustments in less than 10 minutes.
Yes, the tunes are the same, the intune is constantly getting updates with little tweeks here and there so eventually the tunes may be differentU7137 is discontinued so I ordered the Intune and hope to get into that next week. I'm totally new to computer controlled components so I'll take it slow and easy...
Question: some of you seem to have used both the Predator and intune and I am wondering if the pre-loaded or "canned" tunes are the same between the 2 tools? (05 Ram 1500, 5.7 4X4)
