F10 M5 AFE Power Magnum Force Stage 2 Pro 5r CEL

Hello, posting this for a friend running AFE Power Magnum Force Stage 2 Pro 5r which keeps throwing a intermittent CEL. Second time throwing the intakes back on and it is once again throwing a CEL for 102002 Air Mass too Low or sometimes Too High. When stock intakes are put back on it goes away. Car is also running Bootmod stage 2 91 and DP's. Car is well maintained no misfires or malfunctions. Heard that it may take some time for the MAF to relearn? Or maybe MAF dirty due to the pre-oiled Pro 5R media filters, maybe should switch it out to PRO Dry S filters? Also saw somewhere that it's possible to install the MAF sensors backwards? Trying to think of every scenario that could be leading to this. It's not like these are cheap intakes either, great heatshields and AFE is a reputable brand. Any input is greatly appreciated from other owners with intakes!

Some M5's just don't like intakes. I did some reading on this a while ago and the remedy was that some cars have old software on board. If your boy does get a software update and it still throws a code then his options are (1) Project Gamma intakes (have yet to see or read of anyone throwing a code (2) K&N or BMC Panel Filters with Air Scoops.
