What kind of horsepower numbers did you see at 6000?
My bad, I thought it was max tq you look at when determining shift points. Max hp comes in at 4350, tq at 4200. I only mentioned that it made was still making 500 at 5500 to show that the power wasn't dropping off that much but I wasn't reving it that high due to the peak points being so low. Sorry if I confused you. I had Sammy shut if off at 5500 cause I didn't want any block splitting going on that day.
