I have a 97 2.4L 2x4 taco and i'm planning on turboing it. I understand that ill need to upgrade the fuel management systems like the pump injectors etc. to keep up with the extra air I'm adding to keep from leaning out. But the part I'm confused about is keeping the pcm from setting off a check engine light since technically Id still be outside of the original pcm parameters.

Is that all adjusted as part of the tuning process?
Also am I screwed on "legal" Smogging if I turbo my truck?
sorry if its been asked before but I haven't been able to find anything
