Technically TRUE! However, on a near stock car, with mods that are proven and have been used for 100's of people AND when you add in the cost of a dyno tune, it's simply not worth it. There will only be minimal change.

There are some rally cool devices like an LM-1 that you can install to your car, drive it down the road and it will data log a/f vs. rpms yagainst your actuall a/f. They are considered more accurate than dynos by many as the car is under real load AND high speed air flow. This has always been my problem with dynos....they can't do this.
