BCB75 -- I think you're a bit confused. There is only one available header from Openflash. On the website, OFH refers to the header only; OFH2 refers to the tablet + the header; OFH3 refers to the tablet + the header + overpipe.
Regardless of whether you get the overpipe or not, here's the deal:
If you're running the stock header (ie., not the openflash header and/or overpipe), then you can use the STAGE 1 off-the-shelf tunes from the website.
If you've installed a non-Openflash header (with or without a new overpipe), you should use the STAGE 2 off-the-shelf tunes.
If you've installed the Openflash header (with or without a new overpipe), you should use the Stage 2OFH tunes (v1.01) shown on the website.
In all cases, whether you use 91 or 93oct is entirely up to you; latter are a bit more aggressive, so make sure you're in fact using 93 gas in that case.
Most of the discussion in this thread is about the new v3 tunes, which are to the best of my knowledge only relevant for 2017 models (which have a different ECU map).
