Hey, I have a quick question about the Vortech FMU. I am planning on running 12 psi in my GSR, and I'm getting confused about which fuel ratio will suit this the best. There's the 12:1, 10:1, 8:1, and 6:1. Which one will be the best for running 12 psi boost, and how do you calcuate that? As you can tell I don't really know **** about these ratios and things, so any input would be great. Oh, by the way, this is only temporary until I can afford the Hondata S200 setup and find a good tuner in the New England area. Thanks.

 

Yes, can somebody post a link to the math behind this... I'm at 8.7 PSI and want to bump up to 10 or 11... safely.
Thanks
