That is with in industry excepted standards. However unacceptable to mine. I would want it rechecked and verified it was done correctly. If correct I would want a cylinder leak down test on the low cylinders and a borescope inspection of the cylinders and reed inspection as well
It could also just be they were the last cylinder's checked and by the time they got to them the cranking RPM was lower do to battery state of charge being lower
Thank You Leon Pugh
Yea my mechanic buddy said he’d have them run it again Incase it was just low cause it was “cold”
but dont have to worry about it now, got a late text someone jumped on it and bought it..... blah.

Good topic for the 2.5L Forum (which is what this engine's displacement "should" be).
Always be sure to use the serial number to identify the engine.
General specs indicate that it would be wise to repeat that test, following the instructions in the link below. Start with the LOWEST/BOTTOM cylinder FIRST next time.
Specifications:
110-135 psi, max variance of 15 psi.
