Default Where is your AFR at with your PDX email tune?

Just out of curiosity, for those of you who are running a PDX email tune, what sort of AFR are you seeing? Mine at full throttle starts at 10.2-1 and quickly richens to 9.8-1 and stays there until redline. Usual stuff like 3"TBE,Up-pipe, K&N panel, big top mount, etc... The car runs good but obviously suffers a little in mpg (21-22 mixed, 25 hwy) and is a little sluggish to rev out. Great spool and low end power but certainly could improve. Readings are from a dyno pull with a wide band obviously. PDX likes the logs from road pulls fwiw. Where are you guys at on your tunes? Don't come with the PDX bashing, just comparisons.

Anything above 3k at full throttle is 9.9:1 or lower for me. 10.2:1 is as lean as mine goes at full throttle, this is at about 2250 up to 3k. I was a little surprised when I saw that. I'll tune mine as soon as I get a chance.

Yeah you are giving up a lot of power running that rich.

Did you tune yourself or have it done for you? I've pulled the file in my car and looked at it with enginuity but haven't changed it yet. I work for a domestic tuning company and I'm getting some educated lookers over my shoulder before I touch this car as I'm still a rookie.
