i have a 94 z28 automatic and i want to put 3.73s in but ive been told that if i dont use a power programmer, it will not only throw off my spedometer, but totally mess up my shift points as well. problem is, i have headers and plan on gettin a cam which the power programming doesnt support. is there another way to fix the shift points and speedo without paying 400 for something i cant really use??? please help me!
