I have a couple of questions on this subject. Any help would be appriciated.

1. Do you have to get a tune to run water/meth injection.

2. Where would be a better place to inject? Supercharger inlet? Supercharger outlet? Both??

 

id say search and you will find this topic discussed numerous times

Enjoy!

 

ahhh thank you thank you.... and i did use the search but more topics come up that arnt on topic then that are on topic

 

Here is the simple short answers.
1. Do you have to get a tune to run water/meth injection? No, not at all. As long as you run a small nozzle, (3gph) you will be fine and still benefit from the cooling effects and the octane boost. However to get real nice gains, a tune is a must.

2. Where would be a better place to inject? Supercharger inlet? Supercharger outlet? Both?
DO NOT DO BOTH! The best place would be to tap into the intake ( about 5-6 inches away from the TB will be fine.
