    You know NASCAR will be at TMS this week/weekend. There will be a fresh supply of take-offs. Vendors sell the take-offs for $20-$25 each at the track.

    Well, ran a compression check on the truck tonight to try and find my missing HP. All the cylinders ran 185+ to 195 so I guess that's not my issue. This was even on a cold engine. The compression tester said to check the compression with the engine hot/warm. Would that make the reading higher or lower?

    Doing it warm would just ensure rings and pistons were fully expanded resulting in "slightly" less leakdown and higher numbers on your compression check.
    But if all your cylinders are within 10%, you&#39;re in good shape and your problem is elsewhere....
