Retune for Meth?

So my car is now illiterate, and now I want to add a water/meth kit to manage carbon build up. I am running a JR 2.5 tune. Will I need to have my car retuned?

Also, what water meth kits would be good. I'm looking at a devils own and aquamist kits right now but I'm not sure what to order. Thanks.

Have you joined our facebook group? I don't like to mention usernames of who sells these things to us just in case the banhammer comes down, but am happy to discuss it on the Facebook group.

I had the exact same question.... The answer is, no tune needed....the engine will adjust to the lower temps etc etc....

Whitbread is a great resource for this and hes an aquamist dealer.

No tuning needed. You can optimize your maps for meth (timing advance), but running it 24/7 isn't necessary.
