Advanced induction heads never made stellar power on any of the cars I used them on. I tuned all of those builds myself on both a dynacom and dynojet.
LS2 Dyno guesses?

Remove the tb spacer (throw it away, I've read reports of them cracking after a while and causing a vacuum leak). That will give you room to get the ls2 maf in before the TB. Use two pieces of silicone (or Fernco) to connect it all up to the air cleaner. You should tie in your valve cover breather to the setup...but it will be ok to drive to the dyno if you don't feel like fooling with it.

I have run the spacer on all 3 C6's and never had an issue. When I installed the Spacer on this one it was to smooth the transition for the stock TB into the FAST (even with the Vmax ring inside) and it made a huge difference in light throttle feedback, amazing difference.
I'm going to screw with it a little later and see what I can do. Could I drive (highway) with the LS3 maf connected without the proper scaling...?
Anway, this will be my final round of mods and then on to a 10-11 GT500 (another thread right there
) since my wife does want a second child and I need a little more rom and can't begin to afford a GTR

I had to borrow parts from Joe G to make it to the tuner (70 mile trip each way), then swap back on the Dyno.

Good luck Jason!
My last tuning session netted me 503/450 on a mustang dyno in 100 weather, JoeG was here in STL around that time to verify how nasty hot it was here.
Your a solid wrench man and I know you had your 243's worked over pretty good so I think you will be right at your goal numbers.

It didn't for me, but I have a 2005 LS2. I have heard that ECU is unique to that year and is very finicky. The LS3 MAF wouldn't let the car run for more than a few seconds at a time before stalling out.

I'll be doing the install in Vengeance racing parking lot, no other way, tried everything today. Oh well-

My RPM 243's are pushing almost 540rwhp now w/stock displacement.
Going from full bolt on's, to cam and heads was over a hundred rwhp increase on my LS2.
Glad to see your stroker is making some serious power with your 243's. It'll be interesting to see what mine do with the next round of mods.

im guessing 495rwhp 440rwhtq. I put down 506rwhp 444rwhtq with same cam but with TFS 225cc heads. Im going to get my fast ported and go back in actual good weather and hope for 515-520rwhp.

No sir, no meth. The heads were milled just enough to bring the compression back after porting. Considered F/I in the future and didn't want to complicate things.
Nice job on yours- I have a 2 year old and my funds are filtered to Disney movies more than an LS2
Next Saturday, I'll be sure to report back-

I hope I'm wrong with my estimate above. But I keep posting as I for some reason want to prepare you for disappointment. Your car will still be blazing fast and a 10 second machine on a cold day if you launch correctly. P.S. I was hoping for 500 too in my car with AFR heads and a larger cam than yours...no dice.
I know it was a real accomplishment when Charlie got 500+ rwhp from his 243 ported headed ls2 and he had meth, EWP and a razor sharp tune IIRC.
Keep in mind too, if you end up going razor sharp on your tune to get your number (which you often can get a number if you go 13.0+...I'd never use that on the street) you will want to back it down for street use. I had to take timing out of my best dyno tune on the track when i was running in the real world in the heat...I scan all my runs so I know when I'm pinging.

You gonna come get me Joe?
I really don't even care, well see what it does and let Vengeance make a solid safe tune. I'm more interested in how the Halltech feels around town with a fresh tune
If I don't like it I may go larger car (5.0/GT500) or redo the H/C (G6X3/TFS) ....or buy a scooter and forget keeping up with the Jones'.
