pump + meth vs e85
You must be the only person alive with true meth-injection experience. 
Not to jump in this argument or go into the sciences of the two fuels but if I had the choice between e85 or meth with pump it would be a no brainier corn wins every time the only reason anyone picks pump meth combo over it is if there are no stations around.
Well if e 85 is easy to come by then run it. My car is tuned safe wo meth on e85 with safety precautions built in if the iat becomes a problem. The meth for me is just a little extra insurance. If you go pump and meth and if the meth ever fails you will pop your head gaskets at min in .0002 sec. If I lived in the south where e85 is not easy to come by I'd prob step to race gas and meth.

You will find most of the people doing well with meth/91 octane are running larger CI that don't see as high of cyl psi of a smaller engine/higher boost combo. I run meth inj/91 oct in my truck because it's a daily driver and E85 is an hr away. It works well up to about 15~16 psi but after that I have to mix in race fuel. I run E85 and meth inj on my car and the meth inj is to crutch my weak fuel pump, and cheap air to air I/C. I have ran the car back to back on 20 psi of boost and have seen no difference in ET or mph with meth spraying vs not. Where on the truck and gas the meth makes 2~3 mph difference.
