I have an 04 Sierra 1500 crew cab 4x4 5.3L with 4.10 gears. I put a bunch of shit in it from a cold air intake to hi performance mass air sensor, plugs, wires, max energy tuner, exhaust, etc. It easily does 130 on the highway if you take the speed limiter off but the speedo should stop around 125 where his keeps going. Plus the accel. rate is pretty quick but maybe if it was reg cab 2 wheel drive. Doubt it tho. I'd call bull and say his speedo is under recall
my 01 sierra has the same dash and it says im goin 100 when im stopped sometimes.As mcrideout said there are issues with them.If the trucks stopped it could say 70 and when you go it would climb up but doesnt represent the actual speed.If you were gonna tape a "speed run" why would you start so late?He was shocked by the gauges maybe?
I've got the bullydog triple dog gt on my 2003 6.0L along with the aem brute force intake and it'll gain almost that good, it a 3/4 ton so it's a lot heavier.
i believe it ive seen it happen before...that was more around 140 tho
