karmen vortex possible issue...HELP!!

If I get the Lexus AFM do I need to upgrade xthe injectors to 550cc also? N/M i guess only need the 550cc injectors if you install the entire afm housing and not just replace the electronics on it.
Plus I want a more reliable sensor and more than anything else I want something that could help me tune the car eventually.

So to clarify a Lexus v8 AFM/Mass air flow sensor will work with replacement of sensor itself correct? For very helpful info: what other Toyota/Lexsus intake sensors will also work as air flow sensor without having to spend way too much on a used new afm
Plus CRE, the best bet would be to just purchase another 7mgte yellow plug ECU and hope that gets rid of the code 52.

Bump!
Do you think switching out the ECU will solve the infamous code 52?
Code 52 has been showing up for at least a year but the car drove great?

Any suggestions to get the code 52 fixed: new( or used knock sensor from supracarparts.com) but they swear the sensor is good. 3 knock sensor rewires by an import specialists shop and still no progress. . All power is there no hesitation so (unless it's so obsolete that I can't even tell a difference when accelerating).
