Pretty sure it just has a really shitty tune it runs rich..idles high....just needs a tune I would say

 

its only a 214/220 compcam.

 

ah, yea man go find a tuner on this site and have them do you up right. Maybe come down here to GA, let HPS or vengeance, or spartan put one in for ya.. course there's probably some guys closer to you too that are good I'm sure.

also, post dyno results.

oh I see you had the cam specs on the truck in your sig. I didn't put 2+2 together. (slow. ) Isn't an SS like that an LQ9 tho? I imagine an identical setup with a 4 might be just UNDER 400 if you're just over with a 9.

 

yup its an LQ9. yea you should be right up there with your setup i would guess. ill get the results up once i get the dyno sheet scanned into my comp.

 

Here is the dyno sheet.
