99% of the time these issues are set up faults, i see cars everyday running our chips which are supplied off the shelf and if correctly set up they just work fine, which is why we are confident when we supply them they will work.
other issues which we come across, are peoples engine specs which sometimes for one reason or another are not what they think, and means large changes in manifold depression, this in turn causes the ecu to reference a different load site at idle than we would normally see, and these sites may have more fuel in them, as an example, this can be caused by head work, cams, poor lifters, or any number of small changes people have made over the cars life.
we are always more than happy to tweek files and get the most out of them for you, there is no question of that, but you need to be 100% sure everything your end is correct. if we go taking fuel out of a map we know works on hundreds of other cars of your spec there MUST be a reason why yours doesnt work, and if you then go and rectify that issue at a later date you can so easily loose an engine so we HAVE to be very carefull for your own good.
