Hi guys, I am having an issue in the HP Tuners scanner when I am trying to log data. The speedometer will jump from the actual speed to anywhere from 7mph to 40mph above actual speed. I just bought the car, it has Cam, Headers, Exhaust, and Intake as far as I know. The heads, manifold, and throttle body are all stock but not sure if they have been ported or anything. Pulling the tune and comparing it to a base tune from hptuners repository looks like the motor has been tuned but the trans hasn't. I was wanting to try dialing the trans in some but I am scared the speedometer could affect how the trans relearns everything after I reset adaptives.
Any help fixing the speedometer in the scanner or pointers in general would be much appreciated
Thanks
I am also attaching the tune I pulled from the car and the log I just took on my way home from the store if anyone would like to take a look.
