Ok, I've been doing some research lately and watching this vid about how to tune. I like to do some minor tune myself. From what I understand, the main map that I need to tweek would be the High Octane Fuel Map and the Timing Map.

With the current tune, I am experiencing somewhat rich mixture maybe due to my new mods such as ported intake mani and MAP's O2 eliminator. So to my knowledge, to bring back the rich mixture back to 11s, I would have to lean out the High Octane Fuel map and keep the Timing map the same than do some log right?

Thanks in advance.

 

You would want to log first to see what points you want to lean out. You figure out the points via RPM, Load and Wideband, but there is more you should log as well. Check out Merlin's guide for more specifics.
