ive now asked
seat dealer in derby and they say there is really no way of them finding out the only issue he came up with was if the ecu gets flashed itll be wiped thats not an issue just get it put back on agen but surely if the fr develops a boost leak for example they would find boost levels that are higher than normal. The guys who map cars say there maps are untraceable by
dealers too how true is this. THANKS FOR THE ADVICE GUYS MUCH APPRECIATED
