I have remapped my NP300 2019 and DPF was removed based on the tuning company request as they said the power will be increased after removing the DPF ,
Currently I need to back to the stock/original software as I’m not satisfied with the power after the remapping as I have a plan to get DTE systems chip as it’s better ,
The Question is I need to reinstall the DPF again to come back to the car original setup , but some guys told me if I will reinstall the DPF may the car software will getting blocked and the car software will stuck then car will not start up again then I have to send it to Nissan dealer and this may will cost me more than 3000€ ,
So is this correct or just inaccurate expectation from him ?
Did someone do the same thing before ?
Thanks a lot
