Dyno and see , in most cases the engine will tell you where it wants the spark to be if you will listen to the datalogs , some ZX2 knock sensors are overly active but going from 14 to 8 deg if you went that low and it wasnt right you would feel a HUGH loss in power

Excessive timing will lift the head and blow the HG and 6 deg is more then enough to do that and beat your bearings out as well

Now saying all that , you ecu code may need 8 where the next guys ZX2 with a diff ecu code may need 14 , you cant make the blanket statement that 8deg timing for your compression and amount of boost will work for for the next guy, even the same ecu code with the MAF in diff location , cam timing , temps etc would all change the amount of timing the engine could require
