For years have been running mild boost p-1sc blower on stock bottom end.

currently run BP 93 octane with a 50/50 meth/water injection system (with failsafes) to come on at 4 psi boost.

Now Ive added flex fuel sensor, modified the tune, and am going E85 - or some blend in between (like E40) bc not all the pumps guarantee it will be E85 coming out. They say something like E40-E75 at some gas stations

Do people still inject meth/water in conjunction with E85 ? (Or some other ethanol ratio)

Yes you can, it is the "best of both worlds", but for a mild setup it's probably overkill and in your scenario I would just run E85 blend to make the setup more simple, less failure points etc. But yes you certainly can.

I haven't used my meth kit since switching to e85, I always keep an eye on the content to make sure it isn't too far off from what I was tuned on because I'm not running a flex setup so if the content veers too far in either direction the afrs can change
