Calibration Tube for Mass Air

Hi I purchase 42lb/hr injectors and I have a C&L 73mm mass airl flow meter. When looking at sampling tubes I noticed for 87-93 mustangs the green tube is the biggest made and it says for 38lb/hr injectors, but on a 93 cobra the same size mass air everything, green tube is for 42lb inj. so will this green tube work for 42lb inj on my 91?

this is just a guess but i think it has something to do with the computer. did the 93 cobra have a different computer. if so then i would think it would not work. according to the chart on the website the green tube would work on the 76mm for the 42's so it has to be different for the 73 i would think. i would send c&l an email and see what they suggest.
