alright sorry?
but even with a 50/50 mix what are the chances...

One other problem, when you are running a tune dependant on meth to run safe and detonation free, if it runs out unexpectedly, you can get detonation and engine damage. At least this was a problem on STIs and their tunes. I am not sure whether the BMW meth tunes have some sort of safety against running lean when you run out of meth.

WOW great info guys-so if I want to run it an want to do it in my windshield fluid tank what is the safest and most comprehensive kit. I would want to buy a kit that has EVERYTHING i would need and would be able to wire into a jb3 to lower the map if the meth ran out. Also how does it know to only spray at wot?

I have run on the same exact map with meth at 123mph traps as I do on 91 octane only. Map #7. So its not like you have to be on some radical race map, or even switch from your pump gas map to appreciate the benefits of meth.

meth sounds so complicated. i have a question, so let's say at times, you won't to cruise, is there a way you make it so that the meth ISN'T in use. and when you feel like it, you put it to use again?

where do you purchase meth anyway.

the meth is in use only after a certain amount of boost which you are not doing while cruising
