Yeah its definately richer then it needs to be, I assume the downside of a stock MAF is the amount of air it can flow before it maxes out. I think returning to the stock size MAF is a bad idea considering I want to do more boost. I am just going to get this thing SCT tuned. I have had much better luck with my safc then anyone had predicted but I know it is at its limit for what I need. Now its time to save my $$$ and find a competent SCT tuner available locally. So far I haven't had any pinging but it would only take a little bit and the engine would be blown.
