If its a stock engine in a stock car, leave the stock computer.
In my opinion if your going to spend a heap of money putting an engine in another car its the best time to change the computer (while the engine is out of the car).
As soon as little things change (like even air filters getting dirty) the car won't be running standard and will get less power/economy.
As for drivability with 'aftermarket' computers (Delco I wouldn't class as aftermarket as they're off holdens. Where as Haltek and Microtech aren't standard on any cars - are they??). My car has been 'properly tuned', I paid the money for it and now I get the results. The power delivery is smooth, no matter what % of throttle, and my economy is as good, if not better than the standard car my engine was from. When I get something changed, even an extra muffler put on, I'll go back and get it re-tuned. I know its anal.
As for having 2 states of tune, thats silly. There is a point where everything is right, timing/fuel/air, where everything burns and nothing is left - stoich. At this point everything on the engine works better and longer. The sparkplugs don't get clogged, the engine runs cooler, the exhaust has less emissions, the pistons are saved from no knocking. I passed my emissions test with the car on its 'power tune'.
I'm putting a 'Valet' switch in my car, it does nothing to the tune, but brings the rev limiter down to 3,500rpm.
