well i have been told to run my stock ones. i have a devils own kit and when it kicks in my boost does go up but the car hesitates. i know its cooling but doesnt respond all that well. i have the 3gr nnozzle on it and its a stage 2 with a 2.8 cai and borla muffler

 

try activating it at a higher rpm or a higher boost....they recommend you start spraying at about 70-75% of wat your total boost is...this could be your problem...when are you spraying?..stageI or Stage II meth kit?

 

Any one got the mod's i do and spraying water/meth?? I wan to do this but am hearing it is ok and is not ok because of my gm stage 2 tune??

 

I kinda do
With my Devils Own meth injection, The tuner pulled about 20 more whp!

 

its actually better that your staged because your heat soaking more an this will help you cool your engine down...its perfectly safe an its good for your car...it actually makes your engine last longer because it stabilizes detonation...if you have any detailed questions AIS the guy that posted a few above you just pm him an he'll give you a great detailed response or feel free to pm me

 

Bump (still dont know if this is safe for gm stage 2 tune)

 

It won't hurt your tune, sir. It'll just be a cooling mod instead of a power mod, until you're tuned for it.
I ran on my Intense Stage 3 w/ the intense tune and methanol for 2 months, and everything was fine, so I'd say you're safe.
