A month or two ago I did the deckplate mod, bought a K&N drop in, and noticed a decent power increase. I little bit after I did the mod my CEL came on, it turned out my MAF sensor was dirty. I cleaned the MAF sensor and repated this cycle a few times (CEL came on; cleaned sensor) then I just said screw it and took the K&N out and put the stock filter in, would I have the same problem with a Trueflow? Is there anything I can do with the K&N that's worthwhile?
