Hello! I'm at a breaking point before I need to spend close to or over $3000 to return my Jeep to stock gears (3.73). I just did a gear swap in my Jeep to 4.11 because my current tuner said they could handle it. Gear swap was finished, now I tried to tune it and they said wait nevermind they can't do it (Only stock gear options). So my vehicle is stuck un-driveable now because I have no way to tune my gear ratio. I keep seeing conflicting information on the forums. between NGC3 and NGC3 CAN I have a 2005 So I'm assuming its the plain NGC3. WILL this allow me to tune my 2005 Jeep Grand Cherokee to 4.11 gear ratio? If so I need to buy this ASAP so I can have a drivable car. If not - does anyone know if its possible to do a PCM swap from a 2006 NGC3 CAN and put that in my vehicle which is a plain NGC3 (2005) so I can adjust my gears?
