What does it take to be be competitive in .90 racing?

We have been running 2 cars in the super classes the last 10 years.

My dads Super Gas car can run 1.50 seconds under the 9.90 index and it's rather easy to dial. Easy to figure out the ratio and barely have to change numbers for the weather conditions.

My Super Street car can only run .30 under the 10.90 index and it's a pain in the rear. Still haven't figured out the right ratio and putting 25 numbers in doesn't affect it much at all, so I have to change a lot of numbers.

On the other hand, I have a friend that ran a car in Super Street that would run AT LEAST 2.00 under the 10.90 index. Although, he won a National Event in Super Street, he moved up to Super Gas and won 2 divisional races and said it was way easier to tune because he didn't have so much time in the box.

So, my suggestion is to have a car that can run under the index by at least 1.25 to 1.75 seconds.
