Happen to live in Ca , am looking for a ngauge with flex fuel tune , I have an air raid filter but stock intake , is it highly recommended to just grab the kit with the jlt or pmas? Also rock catchers , the jlt foam pieces ? Or what’s mainly used here ? Last one for now lol I’m doing the paint correction and the 3 year ceramic coat on Tue when I get back home , my biggest question is , the guy said he has done one gt350 already as well as a 2020 gt , both had the carbon trim I don’t know how I feel about putting the ceramic in these pieces does anyone here have the whole car done including the carbon ? Pics would be cool af too for either the ceramic job or the rock guards Thank You all
