I ended up using the largest nozzle in the kit (not sure what size) 12afr dropping to 11.5 by red line, boost at only 22psi for NOW due to the small stock turbo & an insane looking ignition table.

You will keep increasing the boost untill you are in high 11s with the same nozzle ?
Increase more boost with the same nozzle but now AFRs are in 12s , add a bigger nozzle ? or add another nozzle with the same size ?
If i am using meth , what is the easiest and best ALT map switching method ?
Thanks.

Wow, that was some time ago, coincidentally, I need to tune a water/meth equipped Evo next week, my first since that one back in 2011. I plan the same AFR targets as last time, attempting to maximize timing. As for boost, I won't be able to exceed 29psi, as I'm limited by the JDM map sensor on an SD car.
Just set your target boost & tune the car as any normal car. Alt map, via a Tephra rom, (ICS Auto switch).

I just noted you are in UAE .. 2 hours flight from where i am...
If i am going to keep 11.5 AFR as target, after spraying meth wont the car get rich and end up around 10 AFR ? In this case i need to lower the Injector scaling and see if i end up around 11.5 ?
What about these 2 tables ? should i leave them as it is ?
Alt map injector scaling.
Alt map cranking enrichment IPW.
