Hey i just got my first mustang and i love it... going from a 4 banger civic to a v6 is definetly a power boost for me and i love it. Its a lot more comfortable too i love it! Anyways i have some questions regarding these common upgrades people are doing and i have read about but i dont quite understand them Chips, 4.10's, and T-Locks ( i guess they increase acceleration? ) What exactly are they? What do they do? What are some good brands? How does tuning a Chip work? Pro's vs. Con's? Approximate power increase? Overall benefit? I realize this could be a long answer but please help me out at much as possible. thanks 2000 Silver V6 3.8
