Default 140mph 2014 5.3 run
Well I had a really straight stretch of road so I tried it out out of curiosity!! To my surprise it ran the speedo out of room!! Heres the video. There was a dip in road and I let out around 130 and got back in it!! I also never let truck get into 3rd gear below 100 just accelerated passed 100 in fourth then went 100%.
