Hello,

I am new to HPTuners and just received my MPVI2 in the mail a few days ago. I have been following some posts on the forums for a MPG PID, but it just will not work for me. I have a Silverado with stock 5.3 and when I am logging and start moving the number go into the 100s. The faster I go the more it goes up so it is wildly inaccurate and I must be doing something wrong, but need help find out what??? Any help would be appreciated.

Thanks
