Low compression on cylinder 1? need input

[94forddiesel]

its a 2008 f250 with 150000 miles dpf delete mini max and s&b intake. i was on my way to work one day having some fun messin with a cummins running it up pretty high and when i got to work i was letting it cool down then it started to have a mis and the check engine light came on. it said cyl 1 misfire and cyl 1 contribution. cleared codes and after work headed home plugged the solus in and check codes and did contribution test was showing cyl 1 was off so i replaced the injector then no check engine light came back on. plugged solus back in did a contribution test again and was still reading a little off for cylinder 1 so far all i have tested is cylinder 1 compression and it was around 200. did not test any other cylinders yet. was wondering is that too low? what else should i test / look into thanks for any help!!!

iirc cylinder pressure should be around 400ish

Yes that is deff to low. Not trying to scare you but these things are kinda known to crack pistons.. So yea

Piston Poof. Running after poofed piston... Cylinder Poof.

Bad to melt pistons too.... overfueling usually from stuck injector. '03 6.0's did the same thing. Time to yank the head off and see what's up. When you put the injector in, I'm guessing to you looked to make sure it didn't spit a rocker arm off?

Just pull your oil fill cap off, that should tell you for sure. Lol
