I have really not run my car hard in a while. I was just out and decided to run it a bit when jumping on the highway and at wot on 3rd, 4th and 5th I see smoke. Now I know Evo's from factory run a little rich, but should I get my car re-tuned? Will it be ok? I normally do not run the car hard since I am trying to preserve my motor. I am just a little concerned.
