as a fellow motor blower, its time for open source tuning. Wether it be proj lambda or a wrx ecu swap. Both should be smog compliant. The wrx ecu has the advantage of all the built in boost tables like the all important over boost fuel cut, and injector scaling tables. Im not sure what lambda has defined but i would assume its limiting for boost applications.
i did the wrx swap but use the carberry rom, which wont pass smog. but i got it passed and now just keep it under 5k miles a year so i dont have to worry about it anymore
