I am going to give the YT's a try.
Stock rockers with fulcrum upgrades, the tr kit, and new pushrods will cost more at this point, and I still have to ask mike at TEA if that is a reliable route to go.

Both cams are peaking lower than they should. I see valve float in both graphs. I know people keep saying HS rockers... I am seeing the same thing. I've had no luck with them with cams that aggressive. Those cams should peak somewhere between 6150 and 6400. Some dynos smooth things out so much on the graph its hard to spot. The power peak and the way it falls just after 5800 are the tell-tale signs.
I'd go to stock rockers. Just my .02...

I am not really sure as that move is advisable. You can tell what the problem is and there are so many people pointing to the same direction. It seems like that would be more money and time that would not produce a return.
You are looking to probably go to the dynojet (unloaded)because the loaded dyno did not produce the numbers you wanted or what? It will show higher HP but the problem will still be there. It will still show the numbers peaking way too early. The curve will not change. You should use a dyno as a tool. Right here, it is pointing to what is wrong.
Fix it first, then redyno it.

Nope not looking for numbers, looking to see if the two problems geoff sees is a dyno phenom or car issue.
I am replacing the rockers.. just dont know with what yet.

We removed that, removed the foam seal on the vararam, and massaged out a small kink in the air intake lid.
We gained 13rwhp from the 505 with those move's, the rest we gained by dropping the AFR to 12.0-to 12.2 from 12.8

Everyone talks about the HS rockers being too heavy over the tip. Has anyone used the adjustable HS rockers for LS motors. I have a set that I have had for almost 4 years with out using them (going in a motor for a car that is not done yet). With the adjuster being over the push rod, I'd care to guess they are of a little better balance. I was thinking about doing a stock rocker till I got it dialed, then switch over to the adjustable, then I could play with preloads a little and see what actually worked best for my application since there is some different thoughts on preload.
Just food for thought.

That's a nice gain for just lining out what you already had on the car! Makes you think how many other cars might have little details that could pick up that kind of numbers. Did you notice if it made a difference in way it carried the power out at all?

Since it is tuned SD, we still had the 85mm Maf in the car, but only for IAT readings.
