A/F ratio question using WI

[Mitsumanny]

To the tuners using water/alch injection, what A/f ratio do you guys run at? I've had mine peak at 12.3 which i think is a little lean, but the knock gauge (dsmchip) doesn't move. I'm boosting w/ a PTE 50 trim at 21 psi, and injecting water/alch with the snowperformance kit. Last time i logged, timming was steady and peaked at 19. Just wondering if anyone else is running a/f ratios as lean as that. Thanx in advance guys.

As long as it doesn't knock you should be fine.

Snow Performance stage 2 and DSMLINK here as well.

I keep my AF at 11:1. I also keep my timing at a max of +2*. I use boost to control my tune.

I don't use alchohol. I was using smurf piss but as soon as I find a dealer for methanol I will purchase it and mix my own brew for the injection system.

What mixture are you using?

I have a fear that my INJ system may somehow not spray (blown fuse, cracked or leaking connection) during a WOT and I dont want to be on the bleeding edge if that happens.
