How My Little 5.3 Performs

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.

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.
