nope........ depends on who's code it is.
franchised companies with resellers/installers have packaged "stages" of tune..
this was to cater for bog stock cars no mods, and those with mods...
the generic stage maps are just that, generic. whether they are optimised for your particular mods is debateable.. they will no doubt run more boost and make more torque/power.
some companies will sell you want you ask for... whether you need it or its unsuitable for your car and mods or lack thereof.. they are there to take your money and sell you something
there are others who create their own maps.. author them, and evolve them on a dyno and road... these are custom maps.. and although obviously based on a starting point, can be dialed in to your specific car. they wont be generic.
some generic maps are adjustable like revo... for boost, ign, fueling (on some models) so although generic they have some 2 elements which can be dialed in to your hardware.
just ***, dont let man in a van visit you, check nothing, and simply flash a file, tell you its xyz power, take your moneys and leave.. this is dodgy... the cars must be checked,.. they are old and have multiple faults usually. simply throwing on some unknown file onto the ecu is asking for trouble.
