X15 down on fuel economy recently?

My hands were kinda tied on this with Haggai being closed, but I didn't want to take it to any joeshmo stealership and have it half arsed. I have seen everything when I stopped by. Heard of them getting stuck putting them in but not out? He's built plenty cummins engines privately and hasn't had issues with them, besides the one my friend had done with him found the aftermarket oil pump (friend was on a budget used aftermarket parts) had internally failed and momentarily locked up and broke the crank tooth, plus the bearing wear, lash was fine. I don't doubt his experience, simply could've not been lubed enough trying to remove it, cam bearings looked good. Just my thoughts.
