Breaking up above 6k

[Nos~4G63]

I put some AV gas in my car last night and attempted to up the boost. I was having some breaking up in the past and Im not sure what it's from. I had the boost at 24psi and zero knock with about 22degrees timing and as soon as I hit 6k rpm the car feels like it is blowing the spark out. I checked the plugs and they look fine (bpr7's gapped at .028). I tried adding and subtractin fuel at 6k and it still does the same thing. The car has only been doing this for about 2 to 3 weeks now. It keeps revving past 6 but it still breaks up. What could it be? I am running the stock downpipe but no other exhaust, could it be from the backpressure?

Maybe try upgrading your'e ignition to an msd or crane setup?

Stock coils have gone 9's. I think it may be too much timing for pump gas. I was getting 22degrees and I did some tuning with 18degress the car doesnt break up at all and with 20degrees it breaks up a little bit but not as bad.

I am currenty running 32 psi on my 3065 setup I had something similar to what you described at 18psi but it would work through it if you held on it. It turned out to be a couple of small boost leaks.

Yea, I am having the same problem ever since I swaped to my 60-1. It sputters up after 6k rpms. I can datalog and my rpms are actualy hoppin up and down about 200 rpms incremenets. but it does it worse in third not bad in first or second. Anybody else having this problem that found out what it was and could postit would help. I've been driving like this for over a month.
