I just bought a HD truck a couple mth ago, it will roll on top end shut off is around 130mph...i had mine 120, i`ve been reading in the HD forum that some replace the chip and top end is moved up to 170mph
, but i never nailed it from a dead stop...only from 65mph or so.....i just bought it to pull the GN to the track...the interior is black and gray just like the gn interior, but i know my GN would leave that truck from a dead stop...but the truck is quick not bad for a 5500lb
