Chassis dyno much more economical if you can wait, though engine dyno is sure to be the gold standard when trying to wring the absolute maximum out of a tune.

If you are running stock CIS, I think an engine dyno is a waste of time and money. You already know what the CIS and ignition timing should be, and you don't need a dyno to figure that out or achieve it. Don't necessarily need a dyno at all. If you just installed a nifty EFI and crank fire system, then a dyno makes a lot more sense. The engine will break in just fine on the street while you are enjoying the car.
