If you still have the stock ecu, there's your problem. I'm surprised you aren't experiencing it in 3rd-4th gear.
Nothing wrong with going (back to) sequential!

12psi will produce fuel cut on the stock ecu. Not much margin left, and the fuel cut defense won't work if it appears as a quick enough spike. I suggest you install manual boost controllers or adjust the pills to bring it down a psi or two, or put in a reprogrammed or programmable ECU and get it tuned.

I second that, except replace the dp with a mp and add a power fc. (dont ask why about the midpipe and not a downpipe)

My car, non-sequential at 11psi, would surge at high speeds. I guess you could explain it like a gentle bucking. Just a thought
However, if you are sequential kindly disregard this post..., and the gentle bucking I mentioned above took place last night on the coffee table with my girlfriend.
