Had the new motor combo out for the first time this past weekend. Very happy. The rpm drop at each shift is 900. 7500 to 6600. Is that expected? New engine combo. Throwing 150+ more hp at it this year and the car is 20# heavier. LS Turbo making about 1150. 3420# car. T400 and a pro torque converter, which is the same combo from last year. I lost all my data logs from last year when the hard drive locked up, but I do not recall the rpm drop this drastic. Thoughts?
