Looking for more HP:
1) for street play
2) 1/4 mile play
3) lower EGT while pulling hills

What are the downsides? I use the McRat 500 hp tune as my daily driver since its civilized and gives pretty dam good MPG, but need lower EGT for some hills. I don't want to pull over to swap tunes for hills.

Other questions:
1) Its boost activated, but what about volume? More boost equals more flow or just on/off at selected boost level?
2) Was reading that it could be hard on your engine, creates more timing? True? Please explain. I need my engine to last forever.
3) I thought you ran 50/50 water/meth. Just read about running 10/90? Why so low?
4) What is the optimum boost level to turn on for playing? Was thinking about 15-20 psi so as not to come on during daily normal driving. I hit about 30-32 max with my current tune.
5) Can you tune for desired HP numbers? I know some kits are rated for say 80 hp, but what if I want only 50? Can they be detuned by changing nozzles?

What are the downsides?
Seems much simpler and cheaper to fill than propane, and no tank to install. I just want to put fluid in my window resivour and check it when I fill up on diesel. Is it that simple or is maintence involved?

I am no expert but have done lots of reading and a 10/90 mixture is all you need the water is more important than the methanol. The methanol gives a lower freezing temp and i think thats all its there for. I am planning on doing a setup soon but the size of the injector is whats holding me up I am thinking 16 gph and a boost switch set on 18 psi.

methanol,or alcohol is fuel,power adder and considered "drugs".meth will preignite,or speed up the burn rate creating more advance in timming.in cold climate you may need meth to keep mixture from freezing.water only is harmless,you will never have a problem.50% 50% is for sled pullin
or flat out race tunes,where pepole commonly blow up testing out the threshhold.don't go there!

I can probably tell you more after this weekend about the Snow W/M performance kit. I had their stage 2 kit on and I went through wiper fluid like it was John Belushi's crack. It was preprogrammed to go off at 10lbs of boost and by running the latest PPE tunes (which adds alot of boost) I was constantly filling up. This weekend I'm upgrading to the stage 3 kit and will be able to control it from the cab. G

whats the kit pull the egt's down to going WFO

I got the stage 3 kit installed last night. With PPE on level 10 I could not get the EGT's above 1250 no matter how hard I tried using straight wiper fluid. i'll experiment with a 50/50 water/wiper tonight. i'm very impressed with the power of the stage 3 at this point. G

Here is a reply to my same questions to the Snow Tech Support:

Our systems are progressive. Depending on how you adjust the settings, the system can coming on at a lower injection rate in low load states and come on at higher injection rate in high load states. Our Stage 2 system is boost referenced therefore it injects according to your boost pressure. The injection rate increases as your boost pressure increases. Our Stage 3 system utilizes 2D injection management by referencing boost and EGTs. This system will offer the same horsepower increases that the Stage 2 system does however it provides active EGT control. If your EGTs increase the system knows to injection more fluid to bring your EGTs back down. The Stage 3 controller is mounted in-cab and is adjustable on the fly whereas the Stage 2 is mounted under the hood and not adjustable on the fly.
