I am very close to purchasing the tvt 265 kit, but I was just curious what kind of real world difference it makes. What kind of cars can you actually mess around with, with the kit? It is either the tvt kit, or a full exhaust and power commander and air filter for the zx14. Pretty close to the same price either way. Any advice is appreciated! Actual time differences like 0-60, or 1/4 mile times, would be great. Thanks chris
