110psi in both rotors? with 115k on engine?
 
I checked my compression a while ago and i came up with 110psi in the back rotor and 105psi in the front rotor.

What puzzles me is my car has almost a 116k on the engine. Or so i think, it may have been replace but i dont know what do you think?

They will hold good compression as long as an apex seal isnt busted. If it truely has 116K miles (doubtfull) then the seals are VERY brittle and its not going to take much to bust them. I wouldnt turn the boost up

Apex seals are usually a all or nothing type thing haha. Especially if the oil and such is changed regularly so they dont wear badly.

hmmmm. i have back up money if my engine does blow but. it seems t hold up really well i have had a spike or 2 and she didn't blow plus 2 or 3 high knock readings. bah.... when it goes a 1/2 bridge port goes back in.

Did you check all 3 sides of each rotor?
