Im having a hard time following what your saying and I type horribly fragmented sentences.

In any case changing the injectors or maf will require a custom tune so you don't want to go that route until you need to. Upgrading injectors will net you 0 horsepower so if you suspect they are dirty just replace them with oem replacements.

If your running lean or hearing detonation then something is wrong. Verify you do not have any vac leaks and that your fuel pressure is consistent at WOT.
