You can lean it out with a wideband a bit but I would stick to less than 11.
There's no problem if you're just looking for a really safe tune. The problem is running richer than 10.0:1 is too rich for optimal horsepower production. Most tuners shoot for an AFR of between 11 & 12 to 1 depending on what they're trying to get, mods on the car, etc...

To the people who've used this, can you post up some logs you've taken with the software? A local user has this and is looking for an easy way to integrate the log w/ a UTEC log. How is the information output? Easily importable into Excel?
