While a 9.99 or better is the goal, this is the app I've used for years called Virtual Dyno to get an idea of what changes will do.
As simple as it is, it has been crazy accurate up to this point. It predicted a 10.40 and I ran a 10.40 that night off the trailer. After the 250 jetting install, it predicted 10.07 and it ran a 10.01 that night second pass off the trailer!
To keep the ball rolling, this is what it is predicting for the 300 shot. We'll see if it works out..
