I have an 01 ECSB 5.3. I hit the limiter which is indeed 128mph for Hypertech. My mods were Hypertech, flowmaster 3 chamber, and old style volant. I hit 128 mph twice, once racing a 94-96 impala, and once an BMW 330i. Lost to both.

It does take forever to hit the limiter, but they WILL hit it. With the radix, 130 creeps of much faster.

actually i think the lt1 has more torque off the line than the ls1's even though the ls1 is faster. oh yeah, I have a slow 4.8

What's on my sig and a little bottle boost

And I'm not saying a modded truck wont hit 138, I'm saying that ANY 5.3 without a high cap fuel pump and injectors isn't going over 120.

My speedo only goes to 100, but with my 32" mudders, I can turn 5400 rpm in 3rd easy. I have the factory 4L60, and 3.73's. Not sure what it works out to, but I think its somewhere around 125 or so. I think in a 2wd and a long straight 138 would be possible. The 5400RPM wastn hard for me. And yes I do know the faster you go, the more power it takes for every MPH. I'm not bashing anyone, just throwing my .02 in the wishing well.
