hey guys im plannin on gettin a fpr and gauge soon. would u guys recommend installing the gauge under the hood or get the isolator so i can install in the cabin. i really would prefer under hood so its tucked away and wont take up any more interior space. plus it would prob be a lil cheaper. i guess i just really wanna know which setup is used more often and which one is easier to tune with. thanks.
