I have an 88 gt 302 with maf swap, cold air, 24lbs injectors,e303 cam it runs rich I was wondering if the stock 55mm mass sensor is causing it to run rich

Has the maf been tuned for the 24 lb injectors? Stock injector size is 19 lbs

I don't know if it has on not it was that way when I bought it is there any way to tell if it has

No not by just looking at it. From my understanding, the computer still thinks you have 19's, therefore the injector pulse width is the same. Switching to a bigger injector means more fuel in that same amount of time, which would cause a rich condition. Have you done the koeo/koer test? That will tell you if you're throwing any codes
