How do I want to address your issue?
I'm not calling anyone names.
I'm just trying to dispell the corperate propaganda that these companies force feed the propective customers.
Alls I ever said was the testing was a bit one sided.
Believe it or not:
K+N IS one of the better CAI applications to tune with on these trucks.
It has the least amount of droan to contend with besides the 3" AF1(which is not made anymore).
Its just the customers own oiling practices sometimes defeat the sysytem and allow it to foul.
Yes.
I do believe that over oiling is a big factor with any oiled filter application not just to the MAF but to the gumming of the TB also.
Take a step back and look at the problem/situation from the whole perspective.
Set your learnings asside and open your mind to other members views and experiences.
Peace!
