I got a AIS kit. Been good for me.Only thing I heard is if your running high boost and more than 40% methanol you will wear your valves and valve guides out. I run about 20% methanol and the rest water with good luck. Only use the meth kit when I have a load on or when egt's are gonna be getting high although I use nitrous on the track or for race times. You should be fine just remember, methanol cuts oil so be smart with it, water works almost as good and won't wreck stuff. cheers
