High Boost Blowout

I was on the dyno this weekend with my Supra and I was experience some spark blowout at 31-32psi. The car was happy at 29psi but 31psi I was experiencing plug blowout. I pulled my plugs and gapped them down from .020" to .017". I tried another pull after gapping down a bit at 31psi and it did not blow the spark out as bad but still blew out a little. I am running on AEM V2, coils are stock denso (less than a year old), new NGK 4644 plugs, HKS DLI. I was wondering if there is anything in the software that can/needs to be changed from a supra base map. After I got off the dyno my tuner asked me if I have messed with coil dwell cause on V1 people would mess with the setting because of the wasted spark. Just curious if there is something on the software side I can do. I will try a friends DLI to see if my DLI is weak.

I'd imagine you're just maxing out the coils. Swapping to LS coils is really common on the 2j.

I’m making 766hp on a stock motor. I figured am ignifuon amplifier and good coils would be enough.
