Ok... Here's the story.
running 930ct. and no W/I and a .26/.47 nitrous pills the car ran a 13.9 AFR.

Installed W/I with 60% meth and 40% water and a .32 fuel pill. So rich it wouldn't go :stab:

Dropped the fuel pill down again to a .28 and ran race gas and its got a 9.00AFR ( lowest the wideband will read ) with W/I on.

Pulled the W/I off and pulled 18% full from 4000rpms+ and it ran a 11.7AFR dropping to a 10.0 at redline.

Is it possible that the M5 nozzle with 60% meth is adding THAT MUCH FUEL ? Hell, I'm looking at dropping BACK to the original .26/47 pills with the W/I just to get a 10.5 AFR on the bottle...

Possible the M5 nozzle is adding 1.5 worth of AFR to the mix ?

Tuning W/I on the motor = easy
Tuning W/I on the bottle = expensive....

I'm not giving the W/I up, I can't believe how cool the intake stays not !!!

im running a 47/24 combo with a 50/50 mix and that seems to be perfect. try the 24 jet without pulling any fuel and then go from there...

I have a upgraded fuel solenoid... Would that any effect on anything ?
I don't have the normal "power shot" solenoid, I have the bigger cheater solenoid... Not sure if that mattered...

shouldnt matter any....but 12.0: is perfect with the water injection!! might be a tad high without it and the stock turbo...but with the water injection 12.1 would be the perfect sweet spot in my opinion
