Hi all, This will be quite a while off but when I do mod the project car with larger injectors, HPFP etc I would be upgrading the parts at home but would need to get the car mapped with these new components. Just wondering how this works in terms of getting to a remappers as if the car was driven on the road with the larger injectors and HPFP it would be running very rich on the stock tune. Are all of the upgrades usually done at the mapping company and then mapped or do people usually upgrade them and then drive to the mapping company? I will also be fitting a BT upgrade, I guess once the injectors and HPFP are mapped correctly then I could just leave the DV open so that car never builds boost until it gets to the remappers? I might see if I can go with a 'plug and play' map initially to get the car safely running, at least with bigger injectors it would mean the car would run rich, although I would be slightly concerned with bore wash.
