Ok Here's the rundown.

6.0 .015 over katech forged pistons and Arp rodbolts
823 heads lightly ported
Texas Speed 231/236 .641 .631 113lsa
Prc 650s spring 7.4 pushrods
L92 intake factory inj nw 92mm cable tb
Circle d 3600 stall 4l80e trans
4" cold air with ls7 maf
4.10 gear

I dynoed today at 381.9 rwhp. Though id be around 450whp.. any ideas?
Oh head3rs are schnoenfeld lts and 3" with dynomax bullets and ultraflows

 

Bad tune?

 

Graph post attempt

 

Tuner said he did not expect any more than that. Could his dyno be that tight? What would you have guessed for my dyno estimate

 

Dyno numbers mean precisely dick.

 

Youre right smokeshow. But I want more inches than you.. :: lol jk

 

In all seriousness. I went to 1/8 mile before the 4" cai. It ran 8.19@85mph. Trying to get 7.5x to 7.8 on motor

 

85 is making some steam for all motor. 381 at the wheels is definitely wrong, assuming the truck isn't super light.

 

something is wrong

we have a truck with lq4 , stock l92 heads & intake with similar cam with a stock headrs put down 395hp

try another dyno first

 

Called for a second opinion. Everybody is saying 4L80e is drinking the rest of my power
