You could always throw a battery charger on the car and do another compression check and see if you get different results, did you perform it on number 8 last? or first?
Seen 3-4 Lund number 8 failures in the last month or two. Have no idea what he is doing.

Might be the fact that he's swamped with tunes.
How do you know it was the tune? It could have been the owner. Could have put 87 in it, used a shitty gas station with the wrong oct in the tank. Over reved the motor, ran low on oil. Other stuff does happen to get #8 super hot. Omg #8

I think everyone goes crazy on these threads and don't look at the facts. The fact of the matter is that it sounds that his motor is ok. 149 psi on a cylinder doesn't mean its bad. 15% difference between cylinders is normal. If there is no loss in power, no noise, smoking, etc. More than likely his motor is ok. Put the blower on and let her rip.
Ford has a compression pressure limit chart they use, as long as the lowest reading cylinder is at least 75% of the highest reading cylinder it is within specs.

holy crap 25% low is now normal now in one affected cylinder????
dont fool you self.
not normal. theres some damage in there bro.
Ya bro, I'm sure you know the motors a lot better than Ford. Huh, bro?
