the only way youre going to know is doing a compression test on your engine.

i ran 8 psi on a 155k y7 for 2 weeks with no management, then an fmu for another week or 2 then uberdata and 310cc injectors. the motor finally started knocking after about 3-3.5 months of abuse, and running on 13 psi for the last week or 2. i pulled it out yesterday, but nothing has blown or broken

if it is tuned right you should be fine. but like others said do a compression.
