I got a AFC because even before doing the heads I was maxing the MAF by quite a bit and I assume it will be flowing even more air now. What or how exactly do I need to modify on my MAF table with a DHP to make everything work properly? I really tried to not buy an AFC because it is just another point of failure but I dont know of any other easy solution.

I got the new MAF table uploaded to the car and it seems to be working flawlessly, that is for idling in the garage lol. Thanks again

Good to hear. I forgot to mention that your trims will be off. Your airflow values were shifted (meaning higher across) the MAF frequency scale. Just do a couple good drive cycles to get them back in line. If your tune was inline before the new table, my guess you will see pretty consistent correction across the board.
