Had my software done today, car definitely feel quicker, more torque, new rev limited is 7300rpm and automatically removed top speed limiter. Long story short, I took it out for a spin and put 80 hard miles, car feel smooth till I got home the JCW charger making some weird loud noise before I shut off the car, so I turned the back and shut it off again, still making weird noise before I shut it down. Does anyone know what kinda problem Im getting, is it the software or I drove it too hard? Should I bring it back to the dealership? Please give me some advice.
