If anyone feels like being kind enough to write up on how exactly you go about tuning the UTEC with W/B, please do. I would like to go buy it, but it is an investment at 1050 + 700... if it's too complicated to where I can't tune it, it would be useless. Their website is pos... not informative at all. Thanks in advance.

By purchasing the Tuna with the UTEC, you get excellent integration. The UTEC will log the WB A/F ratios with the regular information so you can see what load zones you're in at what RPM and add or remove fuel accordingly.

Without the WB, you won't be able to see your A/F below around 12.5:1, so you really can't tune anything except low boost areas. Go surfing around www.wrxhackers.com for a while. You'll find a lot more info.
