I've had my truck in the 190+mph range. I'm pretty sure I've had it right at 200mph if not a little over but ran out of road and had to shut it down. The roads in the hill country are a little rough for those speeds, lol. I know for a fact Allen and I went 188 mph racing a crotch rocket on 410 while tuning... Lol, it was before I had my 200 mph speedo in and was using my gps. It's a fun ride !

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
143mph. Poor little 5.3 just didn't have the steam to push it any further. Should have sprayed it.

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
I've had mine in the 140's. GPS fell off the window at 136 and I kept goin. Wish I knew my exact shutdown speed.
me: man i wish i knew how fast we were going?
casey: hang on i'll check.....148mph(while driving one handed, checking the laptop with the other, and not looking at the road)
me: then put both hands on the wheel!
lol, that was with a CAI, muffler, and tune.

Wow 200mph in a truck, that's crazy, maybe one day I'll get there, I know it was still pulling hard at 125, shifted from 3rd to 4th at around 110 at 6500ish with the nvg3500 with 3:42's. Wasn't looking when I shofted but I know the 4.3 would hit the limiter at 100 at 5500 in 3rd.
See, the thing with Casey is, he's nuts. Great guy, but nuts.Originally Posted by sierraman
