I just had my 04 dynoed yesterday. I guess i was a little disappointed but I can only go up from here. Let me know what you all think.

2004 ecsb 5.3 4wd cai, efans, 243 heads milled .30, tbss intake and injectors, 90 mm tb, 212/218 low lift, lt headers, ory, no cats, cat back 3 inch gibson super truck

318 rwh
308 tq

Runs was done in second gear and its still running a little rich at cruising.

I am happy with how the truck runs don't get me wrong, I just think like many I thought it would be higher. Now I want a bigger cam. I guess its time for a mild stall and a bigger cam. Just need to stay streetable.

Thanks for looking

 

its the cam !! I think !! every thing else sounds good !

 

There is nothing wrong with that cam in a 5.3, unless you plan to spin it to the moon. A third gear pull would have gave you better numbers.

 

I was just saying for all he has and thats the hp he has just saying

 

i see 4x4 and it makes me curious about what size tires you're running.

 

why dyno in 2nd? speed limiter?

 

Running the stock tires

Also we tried a 3rd gear pull, the stall wouldn't stay locked up. Also the straps were breaking loose so the truck was walking when we tried the 3rd gear pull so we backed off.

I wasn't looking for your numbers choda

I also think there may have been an issue with other things both the dyno and tuning. There was a gto that went after me and he has a 6.2 stroker with a magna charger, cammed and headers and a hole bunch of other stuff crammed into it. He couldn't make boost, he was only doing low 400's at the wheels and he should have been closer to 600.

Regardless it still is a decent gain from stock. The tq curve is solid.

 

Good numbers for a 5.3! I wouldn't be disappointed at all...

 

def respectable numbers

 

good numbers!
Sounds like my old 5.3 setup BUT with 243s and a 90mm intake setup
Mine made 301 dynoed in second
