2005 CTS-V with 6.1 LQ4
I finally got to baseline my 2005 V today. The car was like this when I purchased it. Less than 9k miles on the driveline.
LQ4 bored .030" over, Mahle forged pistons, H-beam rods with ARP2000 bolts, new LS3 heads and manifold, Comp cam 219/227 112 lsa. Compression is 10.8:1.
Exhaust
Kooks 1 7/8" longtubes with Calico coating, Stainless Works full 3" with X-pipe O
And the results were:
Looks like I have room to add a little fuel and pick up a few more HP. I'm pretty happy with the results. I may switch cams down the road but possibly switching from 3.55 to 3.73 out back and picking up HPTuner are on the short list.
I do have a question. A large number of people from here are trekking me that I should be seeing between 420 and 450 from this setup. Can anyone offer input on this? Suggestions on what to look for that could be preventing me hitting those numbers if they are possible?
Thanks!

i have noticed that your car is too lean for wot. i believe that going to mid 12's AFR will get you some HP'S and after you set your perfect air/fuel start looking for the lost HP'S if you are not happy with your ET' OR YOUR TRAP @ the strip because @ the end of the day dyno is for tuning and the track is for result IMHO.
Good luck with your build
