I agree with MM , Run striaght methanol , only reason to mix it with H2O is if you want it to be safe under the hood, if you mix methanol is becomes non flamaible. If there was an acident it wouldnt catch fire mixed with water.
I use VP Methaonl , it now comes in 3 different ways M1 , M2 & M5

METHANOL
M1™
M1 Racing Methanol has a 99.95% minimum purity - the highest purity available in the U.S. With M1, engines run cooler and are less subject to corrosion. VP uses only lined drums which prohibit rust, corrosion and metal deposits that can contaminate fuel delivery systems. Recommended for all methanol-legal racing applications.
M3™
Like M1, M3 starts with methanol of the highest purity, but includes lubrication and combustion additives for an extra boost. M3 offers a wider range of jetting options, making jetting easier and more consistent. For bracket racers, variations in ET from run to run will be substantially reduced. With better tuning and cleaner, more efficient combustion, M3 makes more power and yields better throttle response than any standard methanol on the market. M3's improved combustion also reduces the noxious fumes associated with methanol fuels, so it's much easier on the eyes and nose. For 60-70% of methanol applications, M3 won't require jetting or timing changes-just pour it in and get an immediate performance improvement in all areas. In the other 30-40%, M3's added vaporization may actually hurt volumetric efficiency and performance, which is what lead to the development of M5. M3 is not pure methanol and won't pass a water test.
NEW! M5™
M5 is simply the best performing methanol on the market. With its upgraded combustion additives, M5 will make more power than M3, i.e., 5-7% more power than standard methanol, while offering the same or better protection against detonation. Like M3, M5's improved vaporization offers a wider acceptable range of air/fuel ratios and tuning. It also yields faster combustion speeds which lead to closer EGT's from cylinder to cylinder, providing more consistent performance from run to run. M5 is not pure methanol and won't pass a water test.
Available in 5-gallon pails and 54-gallon drums

yes there is , 10.3 is to rich, the GN cars run in the 10.0-10.5 range, but they are running 25-30 psi of boost.
A LS1 running 10-15 PSI is safe with a 11.5 AFR on methanol,
One of my friends is running a agressive tune at 17PSI and a 11.8 AFR
He is spraying the meth before the IAT sensor as a safty.
I know about LSX cars with boost pump gas and methanol injection, I sell methanol injection systems, and i have one on my car now for 3 years , running 11-12 psi on the stock motor , meth+pump (93 octang) 600 rwhp

I buy my methanol from an industrial supply place in 5 gallon buckets. I wouldn't mix with water, just run 100% meth.

you can say 10.3 is too rich, but my car makes 585 rwhp (346 ci) on 10-11 psi through an unlocked 4L80 @ 10.3:1 AFR and traps 131 mph at 3900 lbs. The car sure is making a lot of power for being too rich....
It works for you thats GREAT

You need to know how much meth your running vs gasoline to judge a/f closer.
When i ran 8% meth to 92% gas engine ran good at 11.3 a/f when i up it to 35 % meth i get best power at 10.1 =10.5 A/F

I agree with Mighty and I'll add, 100% VP Fuels M3 is the best I've found compared to several other options...

... the turbo buick guys have a new controller coming out later this year that is basically a full stand alone fuel computer for meth. You can use wide band tracking, IAT on and off, throttle position, knock sensor monitoring, pretty much anything you want and command it to adjust accordingly. Ill be sure to have the info put up over here once they are done testing

QUESTIONS RE: METHANOL IN GENERAL
Q. Can M3 or M5 be used with a methanol injection kit?
A. I'd use regular methanol like VP's M1 for the injection. This is what I personally use. All you are using the injection for is to cool the air charge. This is how you get more power, because you can add more timing or boost with a cooler charge. M3 has a hydrocarbon in it and won't pull the heat like M1. M5 has a hydrocarbon and a combustion additive. I would definitely not use this. It could have bad results by combusting in the air inlet tube between the turbo and the throttle body. M1 is your best choice.
