P1519 is a IMRC fault....Could be a bad IMRC module or just carbon build up on the secondary plates...
P0603 & P0605 are Internal Contr.Module ROM Test Errors, I'm not sure how you got these codes...
Read this it might help...

Sounds like your cars IMRC's are not opening up as they should. This will effect your top end. If you have access to a dyno a way to know for certain is to watch the IMRC cables at speed to see if they flex indicating the opening of the plates or not. My guess with what you have described is that they are not. The other code you mentioned I am not sure on. Is there an aftermarket computer chip on the processor?
