yes sir, that upgrade is an expensive one, but, if you want things to shift better, they seem to have a way to get there...now, If I can look at what they are doing, for sure, maybe I can find the individual parts cheaper somewhere else....and lower the labor and mark up costs....good find for sure....and yes, bragging about 140 mph is off topic....so when you get to 160+ we'll let you bragg again....lol
