I have the Revup version. I was wondering if this car already comes with a z-tube? I'm not sure if it came with it, or if the owner before me installed one, but it has some sort of logo on it like:

l
Z
l



And that's on a small part intake.

 

the car does not come with a z tube. maybe give us a picture of what you have?

 

it's very possible that the previous owner installed it and left it on the car. it's a very common mod. posting a picture would be helpful.
