Hi guys

I have mapped a jeep grand cherokee 3.0 crd with edc16cp31
I've removed the limiter, and the car ? increased from 210km/h,to completely drain the odometer(over 240 speedometer)
After a few days, but the car does not exceed again the 210 about the rest of it goes as when I mapped
I also thought of the catalyst a little clogged, or some sensor is dirty, but it seems really weird why? acceleration and recovery goes as before

? happened something like that to someone?
