I haven't done it yet, but I always go with the 5 star tune for a few reasons, one they re calibrate the tire size, as is my speedo is off by about 6 mph at 60 mph, and yes they get the shift points right... I have noticed before a power increase,.. pulls the hills in a higher gear, and shifts a lot less... and for the cost vs what it does, I never do the banks anymore..
