lines. I enjoy my Z for its handling characteristics. I could care less about 0-60 and 1/4 mile. The mods I have done to my TT relating to straight line speed, are mainly to build boost faster. That being said, I loved my Z when It was an NA, and love it as a TT. What I miss is the "power" on demand, and the abuse I could put on the NA engine. I rarely get on it in my TT, and enjoy 7-12 PSI alot. I dont really go above 12 PSI at all. I am very careful driving my Z nowadays, and I do miss the "recklessness" of my NA. (Hard not to lol at that last line)
