Mods finally done 05 C6
Well I got my car 05 c6 mn6 done, with the following mods
peaks speed shop
port throttle body
peaks speed shop radical ported intake
Obx 1 3/4 lt headers with x pipe
stock mufflers for now had some issues with aftermarket ones (fitment wrong pipes) It will be loudmouth II saturday
slp ud pulley
vararam cai
comps cam custom ground cam
specs seen in pic
I will get the dyno sheet up shortly but it made 450 rwhp & 409 rwtq corrected with stock heads not sure if that is average or not but I am happy with it.

Those are almost EXACTLY my results with my car but I had a FAST intake...way to go! I think you'll love the sound and power.
Here's my dyno sheet to prove it. My 3.90 gears (at the time) cause my car to dyno lower than a 3.42 equipped car. These LS engines are very very consistent across the country on a DynoJet 248 dyno.
When you are ready, the FAST 102 is a GREAT mod for you. Easy to install, great results, but needs a re-tune for sure.

Decided yesterday to overlay all my mods since I've self tuned and dyno'ed each time I did major mods.
I found it interesting and thought I'd share.
See below. Each line represents progressive mods:
1. stock;
2. headers & tune (3.90 gears at same time);
3. G5x3 cam & .040 gaskets (11.4 compression);
4. FAST, and
5. used AFR 205 heads.
What strikes me is how dramatic the gains from headers and a tune were. Combined with the gears, it felt like a different car, and I got a full second + 10 mph in the 1/4 from those mods, from 12.9@108 to 11.8@118. The car was dead nuts reliable at this level.
The second take away is how all the remaining mods really only mattered from 4500 on. Thus I very seldom notice them on the street, only on the track. Not counting the cool sound of the cam.
Mods 3-5 did take off another second and added 10 mph - to 10.8@128. But it cost a lot more and I broke a diff and two transmissions on my way.
This graph shows what I've been saying for while; headers, tune and gears give you by far the best bang for the buck from idle to redline, the remaining mods only matter from 4500 on. Most street driving is below 3000 rpm...you do feel gears and headers even at that level.
Hope someone finds this useful as they decide upon mods.

If you drag race you gents should look into replacing your rear with either a c5 rear like I did or a 06+ c6 rear.
It's only a matter of time before this happens at your power level. In my case it was 301 passes (the poster should say 450 RWHP):
Even on the street, if you get ANY wheel hop get out of it. Our 05's have weak cases, GM corrected this in 06.
