Weird misfire issue

Everything is fine up to around 3500revs, then it misfires like hell, kinda feeling like a rev limiter but if I baby it to around 4k, i can floor it again and it's fine. This is on my boosted 02 R/T on MS2V3. I checked to make sure I don'thave my rev limiter or 2step set to that range. Any ideas?

i had the same problem and ended up removing my MS a couple years ago then just recently found this i have not had a chance to test it agin on my car but there has been a lot of success with this fix and mine was the same way i would hit 3k5 rpm and it would stumble all the way to 4k2 and then smooth out a little

I just don't understand why it ran fine till now. I don't think that's my issue. At least I hope not :/

I should have clarified. It's been running for about a year, it just started acting up yesterday.

Perhaps you can take a data log and post it, along with your MSQ file, the next time the car is acting up.
