I pulled up some old dyno runs from last year and saw the same thing. Wasn't quite as obvious and it was on a dyno-mite dyno. But it was still there in the 3500-4000 range. I think they put a piece of reflective tape on the damper on that one rather than a pick-up on the spark plug wire.

Check the cam specs on the 228r and do a search... They run out of what ever it is a cam does out past 6400'ish give or take a few hundred... the 228r is a great cam, but they don't like to rev that high, it's not a large cam that likes RPM's as compared to a MS4.
I did alot of research on the 228r, was going to put it into my stock LS1 till the plan changed and I went to a LQ9 404, I'm running a T2 and it does the same, short duration cam, doesn't like to be twisted, but makes an *** load of tourqe down low.

Quite a difference in the shape of the torque curves, yours builds nicely.
The C6 signs off early, so I see the problem there. Maybe its to much torque to early as well.
Maybe Ed would comment regarding the early torque if that is correct or not, my dyno runs are on a Mustang. I believe Ed has a Dyno jet.
My guess is still the cam is timed incorrectly, the question is it the grind or the installation.....just a guess though.

That cam is pretty small for a LS2 with some good flowing heads. Also, the stock LS2 intake is complete ****. At least have it ported, or better yet, replace it. Swap the cam out for something with some more lift, and watch it pick up a bunch.

My old C5 turned 436/415 with a F11 112+4 (228/230) on TEA stg 2 5.3s with kooks 1 3/4s in 2.5 after the X and GHLs on a stock Ls6 intake and stock ported TB. I would expect 10-15 more rwhp with the 243s and no other changes. Something isn't adding up...........

A stock LS2 intake sould make more power than that. I made more with a setup very close to this on a LS1 shortblock and LS6 intake.

The ls2 intake is complete ****. I guess some people didn't see the gm hi tech article where they tested all the gm intakes ant the ls2 intake was the worst. The truck intake manifold out powered it. To the op that intake manifold is chokeing out your setup. Get a fast the difference will be night and day. On a ls2 the intake mainfold should be first to go before heads or cam.

Just started wrenching on my car today. I hope to have the cam yanked and sent out to the cam doctor here soon to see if it's indeed the cam.
After reading some these post, now I'm thinking of possibly adding a Fast intake and possibly a underdrive pulley kit. I really don't want to change out the TB & injectors since I've dropped a lot of money into this car already this year. So what Fast intake do you recommend....LSX 90mm?
First I need to figure out what is the culprit of these low dyno numbers. Good news is that Brian Tooley lives close by and has offered to help me solve this dilemma. So hopefully within a few weeks I will be able to post some good numbers.
Thanks for your insight and recommedations.

You are in great hands!
If you do anything different regarding your intake manifold I would highly recommend the 102 Fast intake, might as well add a UD pulley while your at it to pick up an extra 8 or so.

Well I got the front of the engine torn down again. Brian Tooley came by to lend a hand and yes the cam was installed correctly so that is ruled out. Next step is to send this cam back to TEA and they're going to put it on their cam doctor and see if it was wrong grind or deflective. So hopefully in a week or so I'll have some good news to report back on.
Brian, thanks again and good tomorrow at Mountain Park dragstrip!
