bobcat doesn't have a dyno plain and simple. This is a vital tool to tuning and getting the most out of your combo by seeing true results unless you don't care to get the most out of your tuning money.
I take exception to this. The blue car in my avatar and silver car in my sig were both tuned without a dyno. They have each run extremely well. A chassis dyno is not the only tool for quantifying a car's performance.
