Absolutely correct. I've run engines on the dyno and then the car doesn't run the "number" right off the trailer and people start yapping about dyno numbers. Then a year later the car is running 0.50 or even a full second quicker without any changes to the engine. It just takes a lot of work to get the right converter in the car hooked up to the correct gear ratio and tire size and shift speeds and suspension settings, etc. The really skilled guys can sort a car out in a few outings but other guys have to peck away at if for a full season or maybe even a couple of seasons. Especially if they are budget limited.
