how far off the mark does it get? Like I said mine is about an inch away from the window. Are you running the Gates tensioner? Cause I swapped from the Gates back to the stock Ford and the Ford wasn't off nearly as much as the Gates, even though my Ford one had the miles on it and the Gates one was used, which could explain why in itself. But I put the Gates back on for piece of mind cause it was new. Thanks again for all the opinions, if anyone else can keep adding to this I'd appreciate it.
