Hey All, I looking for some help on this. I've recently installed an AFE stg 2 with a dry filter on my 2011 LML. Although it's winter in Alberta and I can't really judge any performance gain(due to the slippery roads), I have noticed two things that worry me. First, the dfp system seems to go into regen alot more often. I have an edge insight to let me know. and Second- I have tripped a MAF performance code twice now when the truck is sitting idling in my yard. It does go into high idle. Stupid me, I haven't recorded the code number from the insight but it does call it MAF performance. And I've just cleared the code with the insight. Nothing else has been done to the truck. Anybody got an idea on this???
