I just passed smog in a 2001 Silverado with a high compression 6.0 with a BTR Truck stage 3 218/224 .553/.553 113+3. Deleted the AIR and EGR. They just plug in the computer and see if any trouble codes show up. Its all in the tuning.

I was afraid of long tubes for a long time so I only ran shorty headers. I did notice a small power increase on almost every engine. And installation was always easier than long tubes. And I noticed less valve noise with short tubes. Glass half full and all that. Cali might limit your options but you still have options. However, if you are going forced air, cam, heads, and exhaust are a lot less important. FI will for the most part ignore the restrictive stock equipment. I would buy the SC first and then decide if you need more.
