[QUOTE="zombiekiller, post: 1272994, member: 25186"] a couple thousand miles is honestly way too short of a "test period" for me to say one way or the other. I will also say that I only ran the mpt tune for about 1000 miles, then removed it. The adaptive cruise was way too finicky when running any of their tunes. The extra hp and torque weren't worth me leaving it in. Based on the current state of my motor, I highly doubt that any amount of anything would have prevented what is going on. I have a feeling that the cause of my woes is mechanical or Physical-electrical (i.e. wiring harness). I would tend to say "run a catch can" if you're going to run a tune that does not leverage the tables which facilitate the truck adapting to lower octane levels. Any sort of oil blow by pollution can have a diminishing impact on the effective octane in-cylinder, and I'd put the mod in the " rather safe than sorry" bucket. That being said, I'm pretty sure the Ford engineers designed in enough variability to negate a catch can as a requirement for a stock truck. [/QUOTE]
