I was wondering what is the best way to tune a 94 cobra. It has a powerdyne supercharger I will probably increase it to 9 psi, bassani headers, a off road h or x pipe is going on within the next week,and afr's in the next 2-3 months. But what would be my best bet to tune it a tweecer? A chip of some sort? And how exactly does the tweecer work, is it difficult to use? Or do I even need a tune at all? I am not that familliar with these cars. I dont know if there as "sensitive" as the 4.6's which you change a a spark plug you need a new damn tune.
