you cant tune the mines computer, all you can do is plonk it on the dyno
and hope the afrs are OK and it runs ok, given you are changing AFMS and injectors, its unlikely
it probably wont even idle - so unless you can find a shop to remap the mines ecu (try dr drift)
your stuck with a probably unsafe tune / unstable or youll have to replace the ecu
your better off changing injectors, AFM and ECU all at once
and getting it tuned once for the most safest power you can make
then use your brains to control the power or turn the boost down
doing a complete tune on one level of PSI, then months later
doing it again on another level of PSI is stupid
or turning up the boost later and hoping for the best (ie, without retune) is also stupid
