Tweaking.... Tuning....

I believe it never really comes to an end. "There is always more" ..... so to speak. Most folks quit when the car is running both "what they expected and consistent", both street cars and strip cars.
So how much does a car have in it? My opinion is "we'll never know", because we'll never reach the summit of tuning. Makes no difference where we start, or if it's a bracket car, street/strip car, or a weekend cruiser.
