First rational post... i never checked the numbers with the old stock filter cause I only had it about a month before putting the k&n on. The truck has always run a k&n and since the first time I checked fuel trims they were in the +8 range. If you read some of my other post i suspected a vacuum leak and went nuts sealing everything.If it has worked since the truck was new it should work after you have the engine all apart.
IMO check for leaks.
My fuel trims now stay 10.2 at idle, 9.8 cruising at 65, and lowest is 5.5 full throttle up a hill. Long term. Thats a fairly good ratio of high vacuum to no vacuum so I'm not seeing a vacuum leak being an issue anymore. If im wrong correct me...
