I want to upgrade to 42# injectors and ditch this fmu. I have a 76mm c&l maf. Can I just get the correct tube and install the 42's? Or do I have to change anything else? Also I see on the c&l site 42# injectors aren't listed for a 94-95 GT with the 76mm unit. The 87-93's use the green tube. Anyone know if the green tube is needed for the 94-95 GT as well? Thanks for any info.
