TBH I tought it is fun to have chipped JTDm engine, but after few days, I am looking into returning it to stock values.

Problem is EGR and DPF are cut, and disabled in ECU, will this affect stock ECU map?

In question is 159 2.4JTDm Q-Tronic.

Thanks

I sometimes turn my tuning box off for a few days...just to feel the difference when I turn it back on! You do get used to the extra power.

Hopefully your tuner backed up the original file before making a modified version. If so, best thing to do is start with the modified file again, and then just map out EGR & DPF without making any changes to boost/fuel. Then your car will work, but performance will feel close to stock. You can't use a stock map file on a car with EGR delete and DPF cut out. It will report P0401 fault code for no EGR flow and it will try and regen, which is like a James Bond smokescreen when the DPF has been removed.
