416 N/A E85 550rhwp!
Well I finally got the car on the rollers last month and it made the power I wanted it to but there is still an issue somewhere that I can't narrow down. Here are the graphs that I got. You can clearly see that the graph that isn't smoothed out that there is an issue.
I have been told by my tuner that it is a valve spring related issue. I don't think that it is cause the heads are brand new with less than 3000 miles on them. I purchased everything from LME (heads,cam,rotating assemble, everything). I can feel it in the car it cutsout and comes back on. I can also see it on the wideband the AFR will be like 12.8 and then it shoot to 13.5ish and then comes back down.
I think it has to do with a coil or ignition somewhere. It pulls awesome to 6200 cutouts and comes back in. I want to get this figured out so I can spray this monster. The last pull is with the converter locked up. Its weird I didn't have this issue last year and the car ran a 10.51@128 all motor with a 1.47 60'.
I want to figure this out before winter so I can get my 9s pass this year!

But from all the vids/threads ive seen explaining HOW and WHEN valve float occurs it would not make sense that at a higher RPM for the power to comeback.
Try googling "LS1 valvefloat".
In one of the threads i saw Damian chime in on that, when someone had a similar issue to you.

I'm having somewhat the same issue!! I hear it breaking up a Lil when I go 2nd to 4th under 3/4 throttle sorta speak or between shifts I feel it somewhat die out. I have ls3 coils so it's not that and I had this problem with my ls1 but that was really bad and all the time! and this is intermittent. I'm thinking a wire in the harness some where. But how do you test the wiring. Sorry to high jack bud just thought it might be the same issue. Sorry and thanks.
