Why does a remap make sure everything is ok? But seriously, you're not helping people decide on whether you've been quoted a ridulous or reasonable sum. After all if you just are after a minor bhp upgrade why bother with a custom map or if you are after the all singing all dancing biggest bhp Cossie ever to see the light of day you should expect to pay top dollar for it. Why don't you phone around a few of the tuners and see how their prices compare?
