I noticed the Mazda 3i with the PZEV emssions equipment has 144hp vs 148hp without it. The 3s emissions equipment is label CAL. Is this the same and does it reduce the 160 HP to 156hp on the S model. Searching dealer inventory to make purchase and found one with option which has CAL(NY). Concern about loss of HP since my state does not require this(NJ).
