KA24DET rich bogging/stalling on decel, not catching idle

I know someone already mentioned this. But I had the same problem with my old rb20 setup. Turned out to be a leaky bov. Which may make sense because if you rev, start to build boost then release, you loosing metered air. Causing a rich condition. Have you tried a new maf?

Disconnected the vac line and covered the BOV so it didn't open, still no change. Not the BOV. I haven't tried a new MAF yet, but I will this weekend. Problem is, this started (albeit it was much less serious) before I was turbo, when I had a stock KA with the stock MAF. Current Z32 MAF has been cleaned multiple times with MAF spray cleaner.
