Remapping these cars is a labour of love when swapping injectors, pumps, turbos, trying to add vnt, whatever else. I guess most tuners are getting about £1/hr average in the end, if not less. And 90% of that time is spent just diagnosing hardware issues or interpreting feedback issues, not learning new things per se... that is usually done on your own development car, or a car you get access to for a few weeks!
Start with the simple stuff, get it working right, and then slowly build upwards and outwards methodically, fixing problems as you go. Simply going straight for the high revs, big power etc etc, simply leaves you with 100's of potential problems with no obvious cause in your mind when something will invariably not work right.
As a rough guesstimate I'd say that tuning to say 5000rpm vs 4000rpm has about four times as many possible pitfalls and possible areas where things could be causing problems to worry about. It is sensible to isolate that step in the tuning process for obvious reasons.
If everything else works perfectly and then suddenly as you are adding fuelling at 4500rpm+ for big power, and you start to get faults, you can simply say to the customer you are reaching the limits of their hardware... since the rest of the rev range is otherwise running very very well!
You won't know that until you know the bit where it's easier to get it working right IS working right
