Default Another UTEC map question

As some of you know, i've decided to take the VF-22 route. The 22 will be arriving this thursday and i'm planning on giving the install a try Friday. I've gotten a few base maps to start with, but the map i've chosen to use was tuned for 94 octane. Since we only have access to 92 octane, what changes should I make to the timing and fuel maps? Should I be lowering the values or
should I increase the values? Boost map will remain unchanged since im using the Blitz boost controller.

Are you using a base VF-30 map, or someone else's VF-22 map?

You're putting on a VF22 and you're not sure whether to reduce timing and fuel or advance it based on the fact that you are going from a HIGHER octane map to LOWER octane in your area.
You REALLY should read the manual and get comfortable with tuning the UTEC on the stock turbo before you start adding a big 'ole turbo....

In short you'll probably want to reduce timing a couple of degrees across the board not to mention some fuel trim adjustment. Do you have an EGT gauge, wideband? Or better yet, access to a dyno with a wideband?
