Im not sure if this is a MAF failure or surging causing this issue. The car does show a code for MAF high frequency. After logging the car you can see that load is going through the roof and maf lb/min is erratic only under boost and at idle. There are small spikes that jump up to 50lb/min. Watching the maf frequency you can see it follows the same erratic pattern as everything else. I siliconed around the maf to make sure there were no leaks there and boost leak tested it. The AFR is way rich as well. I checked and the maf is pointing the correct direction. Here is a clip of a log to take a look at. Who all is running this set up?
Wierd thing is that I had the car dialed perfect and after he put it to stock then reinstalled his parts the issue came up.
