Do you have a scan tool that can run a power balance test to see which cylinder is weaker than the others?

Customer: replied 8 months ago.
No smoke all 4 cylinders have around 130

Compression should be 170-225 so it appears the engine is internally damaged or the engine has jumped time. Does the compression come up when doing a wet test.
