I have an 09 Honda Civic SI with Injen SRI, P2R Throttle Body Spacer and 2.75 Cat Back Exhaust. What CAL should i use? What should i drop VTEC to? What redline RPM is safe for me?

Use the Injen SRI map, and if i were you, dont mess with rev limits or vtec. You seem like you have a good bit to learn so stick with basemaps for now. If you wanna raise rev limits and drop vtec the right way i suggest a Professional Dyno tune for you
