I'm in the process of resurrecting a 2008 S197 with a dead 4.0, stick car. While I'm yanking the motor, one of the things I'm considering is changing the 4 inst cluster to the 6 inst cluster. I read that they just swap without issue, then I've read that there is reprogramming involved, Codes installed, security code details, etc. How big a deal is this, is the brain / ECU really sensitive? Some companies that sell these rebuilt clusters really scare you and want reprogramming fees, etc. Input fellows?
