Currently this is where im sitting. did some more logs tonight. Im almost possitive its a spark issue. going to check all my grounds tomorrow and also change the plugs to a BKR7E and gap to .030 to see if that helps. I have boost control turned off in the tune to eliminate that from the issue. Doing some shorter pulls around my house i was able to build 6psi boost before any cutout. when it cuts out the rpm has a slight drop for just a second like the ecu is losing power.

Checked all groundsn and all are good n tight. and replaced plugs and gapped to .035. engine still sputters like a fuel or ignition cut. kinda lost on this. What could make it sputter like an ignition cut?
Your boost control cutoff is 150kpa so I'm guessing anytime you hit 6psi/150kpa there is a fuel cut. Adjust this number to slightly higher than your planned boost
edit: confirmed by looking at logs. PW drops off as soon as you hit 150kpa.

I was thinking something similar but my boost control is turned off would it be in a different table?
