Hi, im new here too! I know what you mean about petrol, I have had V8's for years and bought a Stivo about 5 weeks ago. I bought it thinking i would not modify, now i definately will be. After past experiences, I agree with what SB and Nate said. In theory, the mods should pay for them selves in the long run with savings on petrol! Thats what I will tell the missus anyways. Welcome, I have found this a helpful and friendly place to be. :D
