SC Thunderbird

[ROYAL PARTS]

the car is a Thunderbird SC 1992 with 30000 miles on it
when the car is cold and until it gets a little bit warm the engine runs fine even at full boost (9-10 psi)
by the time the engine is fully warm and at operating temperature, whenever the engine is reved there is load and there is boost, the engine knocks badly
if thhere is no load, or boost, it doesn't knock
there is no check engine code, spark plugs are the right ones
it looks like the timming is too much for some reason
all the OTC tests were run with no errors
the DIS module , spark plugs, fuel pump, fuel filter, cam sensors were replaced and the injectors were cleaned.
i would appreciate any help.
