Early hemi owners beware...
Well, let me start by saying the Mag runs alright NOW. I bought the I3 tuner as a refurbished unit. Was supposed to have all the latest updates. For the first 2 days i was back and forth between the laptop updating and the car, telling me it wasnt supported, needs updates. FINALLY for whatever reason, it decides to work. I went first for the 93 octane CAI tune. It let change tire size, speed limits, rev limits and so on. Did everything as instructed and when instart the car, 2 cylinders are dead. A long list of codes pop up. To get anything to happen, i had to pull the pcm fuse. I will say customer service has been awesome with helping via email. Staying right on top of it with suggestions. The Mag finally runs well now. Still has an engine light on, MDS is turned off and throws the code. It shifts firmer, better response in the throttle and maybe a but more bottom end. Its all a timing thing anyway. If i had to buy a new unit, i would take that money and have it dyno tuned. You know what the numbers are are what the tuner did.
