Should i put some oil down the cylinder and turn it over a few times with the injectors turned off to help reseat the rings from the previous wash?I thought you were referring to cam timing. No, cps won't affect your spark timing. If you're getting spark at the plug, the CPS has done it's job. It doesn't really matter where the sensor is positioned, it's only reading the time it takes that crank to spin a full rotation. Your tune is simply dumping way too much fuel.
