I ran pump 93 and 50/50 meth/water on my turbo Forester and could run 4 psi more boost (from 19 to 23) and more timing than on 93 alone. Made about 50 more whp with hit. I had an upgraded TMIC and it simply heatsoaked too much when increasing boost without the meth.

For a comparison I'll be getting a new tune on 100 octane and 93. I've got a new FMIC now so I should be able to compare the various runs. It will be on the same dyno.
