Right,if i understood correctly your saying that the cylinders have 75psi in each?what i don't understand is the charger bit?,the charger has nothing to do with engine compression,the charger creates postive press. above atmo.press.,it's a supercharger that compresses the incoming air,the pistons and rings compress the air/fuel.

Check the Lambda wiring and earth,almost always hard and crumbly after 16+years of hot and cold.

Did you remove the ecu's boost sensing rubber hose?,may have been fitted back on the wrong brass nipple on the throttle body,also check the FPR's small rubber hose for cracks/splits.

Change the blue temp. sensor located on the front of the cyl.head or swap over the two harness plugs blue with black temp. sensor.

Co pot been fiddled with?,was it adjusted accordingly when you fitted the re-mapped chip?.

Check that lot and let me know if the car's better.
