I just bought a used evo 9 with an aquamist setup. I was told one of the nozzles was leaking from alfred at tuning tech and required some new pieces. The two nozzles are currently located on my stock upper intercooler pipe. I just recently bought an injen intake/intercooler piping kit and wanted to know what I should do about the meth. I dont want to dish out the money yet to get the nozzles updated onto the new injen pipes and retuned only because I have so much more things I want to get done to the car before the tune to maximize the power. What I am thinking of doing is installing the injen piping and taping up the meth lines somewhere in my engine bay. Obviously I wont turn the meth on, but do you think it will be safe with them taped up in a safe place in my engine bay???? Currently the car has a tbe, boost solenoid, and a fuel pump. Some modifications that I want to get done before the tune are 02 dump, exhaust manifold, bov, intake manifold, intercooler, cams, and a bigger turbo.

So far I am in love with my evo, just ready for some more power

 

make sure the meth tank is empty. then yes, you should be fine keeping it secured in the engine bay.

if the car is tuned for meth i would not get into boost. you WILL run the risk of destroying your motor. Get it retuned to get the jets before any sort of WOT pulls

 

Ok thanks the car is running two different maps btw. Forgot to mention that

 

You should be fine then. Don't leave the meth reservoir empty though, just remove the fuse to make sure it doesn't turn on. If you run the meth motor trying to suck from an empty reservoir it can ruin it.

 

Where can I fine the fuse for it?

 

I'm not sure how the aquamist setup is done, but I bet you can follow the positive wiring from the pump to the relay to the battery. There's bound to be a fuse in there unless the installation used some factory wiring, which is possible but I doubt.
