I'm having problems with my car only recently started happening since I changed crank oil seal video attached

 

I can't get my car to redline without the rpm gauge going mental, does it

In neutral and on load car still boosts though hits 1.5 bar I'm running t51r and svyecs s6 ecu, help to what the problem

Could be I am thinking faulty crank angle sensor any ideas?

Have do damages the crank trigger star wheel? I don't know if the Syvecs allows you to view an oscilloscope pattern of the CPS sensor signal, some software does, like MOTEC. If it allows this you should be able to see any issue without getting your hands dirty. Otherwise a decent garage that has a `scope and knows how to use it could look at the CPS signal.
