Tuning MAF - Idle hunting leads to stalling
My car is a C5 Z06 with ported heads and 231/236 camshaft. Previous to my clutch job this winter the car was running great. I noticed the fuel trims needed some work so I tuned the VE table, and now I am working on the MAF. The WOT zone of the MAF needs work, but that's another day.
The car idles in the driveway fine, but dips below idle when you rev it. Then hunts and recovers. When I'm driving the car it's another story, hunts badly, idle swings, and then it will stall if you don't assist it with the gas.
I have attached my tune, config, log. Does this seem to be a RAF issue? I ran the russ k idle config last year to get these numbers.
When both VE/MAF are enabled it drives fine, hunts occasionally.
Looking for any pointers or help
