im not going to go straight into a turbo build but my question is more geared towards upgrading/tuning. I have a 93 lt1 and of course I want to go fast. now most of my experience comes with imports so please be gentle if I say something that doesn't apply here. anyways my car being a 93 has no maf. to my knowledge its a lot easier to turbo a car with a maf compared to a speed density tune cause the maf will sense higher airflow. but on my paths of upgrading will i have to get a fresh tune with each upgrade? or is there give in the system that will alow me to upgrade a few parts over time without going stupid? thanks ahead of time.
