Am getting new exhaust fitted on Tuesday and am getting the DPF "done" which means I am getting a remap to code out the DPF, however am just wondering should I get the EGR mapped out as well or leave well alone, I just fitted the new fiat gaskets 2 weeks ago to the egr and if I do get the egr mapped out would I need to get the gaskets totally blanked off or could i run as normal with the modified fiat ones,
