If you post screenshots of your various tables (afr, advance, ve, etc.) you might get comments from people who know tuning but don't have tunerstudio/msquirt.

How were you able to setup load as PSI?
Mine is currently kPa.

My 2 cents.

Based on the other posts the engine runs and idles.

I have not used VE to tune before, but the VE table drops to near zero at higher vacuum numbers this could be drying up the intake and causing a stall going back to idle with the throttle closed. I had to finesse my tuning in this area to "catch" or return to idle gracefully after a higher RPM letoff.

The ignition numbers look reasonable for twin plug at operating RPM. I would have expected closer to TDC at idle, but this wouldn't stall the engine.

Hope this helps.

Whoa……PSI. I’m accustomed to kPa.

Very hard to understand what the motor is doing in vacuum for me reading PSI.

First time I prefer metric over imperial

Could be fuel overrun too as suggested. I adjusted my settings a few times to get the balance right. Any datalogging capability for AFR?

i did disable the fuel over run and it helped alot but still will die when I let off the throttle from higher rpm

I would make sure it is off for now, at least for troubleshooting. I noticed a couple of cells with very low Ve
