I'm running a single 1.0mm jet on my max'd out IX turbo and recently switched to E85 and saw some performance gains. This is a great tool to help you (and me) figure out what different jets should be used for optimal fuel percentages. I'm thinking of adding a 2nd jet (.5mm) to bring it over the top.

^^^ About 4 bar or a little less... expect 45 psi or more on the stock evo.
According to that calc one of my customers is running a 56.121% to fuel ratio with 2 x 1.0mms!! lol. That car is just plain fast!!!

Nope, that's about right 
2x 1.0mm nozzles should get you close!
These are ideal circumstances though, I think my setup only runs about 10-11% meth/water and I get great results. This is with a single 1.0mm jet.

I have been reading thread after thread on selecting the correct Jet and restrictor size but don't seem to be getting it. I am running a IX turbo with stock injectors and will be setting up an HFS-6 system with a 50/50 mix. I am a little lost on how to know what my Injector/Fuel Rail pressure are and what the duty cycle will be? Can someone give me a how to determine jet and restrictor size for dummies?? Thanks for the help.
Most of those values you leave as-is. Stock injectors flow 560cc's and you have 4 of them. You need to log your car to see what your peak IDC is but if you have a walbro and all the mods listed in your sig, you're prolly running about 100% IDC peak pretty easily (not bad, I ran mine up to 127% 
).
Anyways, decide how much meth/water you want to inject and set that percentage, or guess at what jets you want to run and work your way backwards. Last week I switched from a single 1.0mm jet and added a second jet. I was going to add a .8mm, but all I had was a .9mm so I just went with it. That adds up to 967cc/min based on the chart listed on that page. I'm using 2 injectors, so divide that in half for 483.5cc/min per injector target (average). With my setup and some rough numbers, that gives me about 22% of my fuel ratio being water/meth. Since I'm going for max power out of the setup, this is a good % to be at
I attached a screenshot of the settings I used. Again, rough numbers but they work.
