I know, but I think that's due to skill level. You don't recognize that it's not a factory intake, etc. I guess on your own car you'd know though.

Also, I read someone said to do T&T witout nitrous. Thought that was odd. Maybe that's just setting tire pressure and such that he meant, but I don't understand why.
Hopefully he didn't mean to not dyno with it. I would think if you're using it, you should dyno with it.
