Complete the Shift about 5% RPM over the rpm that peak horsepower was at. I like to pull the lever at 7400 to get 7650 with my TH400 trans. There is a delay for the clutches to lock up and release. Mine may climb faster than yours but always pull the lever before the desired RPM no matter how many gears you have.
Nice job Mike, I ran my Cadillac STS last sat at the Motorplex. It was 42 Deg. An all wheel drive V6 was just about right. 14.38 ET at 97.82 MPH and traction was NO problem. I am running the Beretta this sunday baring no snow of course.
