MSD unit will not work due to the multiplex ignition signal,
that is unless you want to run three of them.

The ECU has some learning capabilities around ignition related
knocking.

Suggest the Apexi Super AFC to lean it out.  If you can swing
it by NJ emissions, the Maft or Maft-Pro units are excellent.
E-manage might be another solution for you since I believe it
can use the stock (or lexus) afm.
