To much methanol can cause a lean reading, even if your not really running lean, It does not act the same as gasoline. You need to check your A/F ratio with the system off to see what your car is actually doing then check it with the alcohol on. But a M6 nozzle is way to big for your application.

Now if doing the same with the M3 nozzle you might want to look at your fuel pump being the weak link. Most kits come with upgraded injectors to match the boost and should not get maxed out at there designed level.

Alot of the time what is needed is a voltage booster for your pump or a race pump.
