if my ghetto math is right im around 130-132 on a setup that is suposedly IMPOSSIBLE factory from the tank to the injectors, no cam, no nitrous, ecsb pig at full weight+full tank and system. and had no problems getting there. it had more left in it...


on a side note, 01Thunder is lucky that his air dam didnt fly out of the bed of my truck on my way to drop it off

Show me something in digital numbers - I wanna see what the REAL speed is - not what a POS gauge is telling you. The gauge is wrong - watch the vid again and you can see that GM gauges always read faster than actual speed.

But that's pretty bawlsy taking cell phone pics at 120

Dude I know all about tires floating and speed - thanks for your concern

Besides - I've got some serious rubber grip

i just watched it. at 120 your guages sit right at 5,000 rpm and your laptop says it too. it goes back and forth proving that they aretn THAT far off. if i had the equipment to prove it digitally i would but im sure you would just make more excuses of how your still right. accept it, our trucks can get past 122 without changing injectors and pumps. im sure yours will too, you probably have just have a little tuning issue up top, or maybe its the elevation your at. my basically stock truck pulled to 120 a whole lot harder than your 405hp beast.

If you want to know how fast you are going, use a GPS unit. It'll tell you exactly how fast you are going.

I pegged the HPP3 rev limiter at 128 mph on my Av several times before I installed the Radix. It would be a whole lot easier to get there now but I haven't pushed it over about 105 yet.
