Wondering if anyone can answer this for me. I bought a used Stillen stage II setup. I'm wondering if it is possible to have it tuned with a UTEC vice the SS box and extra injector that came with it. My main concern is that being in California I need it to neet CARB requirments but want to be able to switch drive pulley so as to run it with higher boost when CARB is not a concern (passing smog test for registration).

It would seem that the UTEC with MAP sensor would work with bigger injectors and fuel pump upgrade.
