439.7hp/411tq @5800rpms. 12lbs of boost is the only thing I have changed from my current setup. (stock cam, stock stall, stock 3.42gears)

I tried to get the dyno sheet on the computer, but my stupid printer wouldnt scan it. So here is the video with a glimpse of the dyno sheet. We ALMOST got her to 440, but I am pretty damn happy with these numbers, on an otherwise stock 5.3 with 12lbs of air going through her.

Oh yeah. 42lb injectors are at 97%. Next on my list is injectors, FAST fuel rail and some more boost.

 

Congrats, I thought it'd put down a little more but that's respectable for an all stock truck plus an STS kit.

You definitely need some new injectors though.

 

12lbs! Wow, yeah i think that dyno reads conservatively. sounds great!

 

I think a cam would make you some serious gains. My 42lb injectors are at 95% on my 4.8.

 

some good numbers for just going FI on it.

 

nice numbers dave, are you running meth through it too???

 

what numbers were yall thinking of? I have only seen 400 on 10lbs with a stock 5.3. I thought my tq would be a little higher, but this gt67 kinda starts to fall down the closer I get to 6k

yeah a stage one meth kit.

 

+1, toss a cheap LS6 cam in it

 

dam good lookin truck... wonder where you got the idea for those wheels? but sounds dam healthy, nice numbers too

 

LS6 +3k stall+bigger inj+MP70 is next on the list+fast90 fuel rail

lol actually someone had them on there black 4x4 here. I havent seen him around since though. but great minds think alike. You should paint your centercaps black
