alky/meth setup works very well on turbo setups.
with the Meth you will be adding fuel so you wont have worry about too low of octane. it takes quite a bit of tuning to get right. be careful some people go to rich to start out with and destroy there o2 sensor.
make baby steps when it comes to adjusting fuel and boost with that setup

How is meth injection cheating? it is a proven way to intercool on a turbo setup. on m-90 is a different story
