u7195 parameters question

[tackwest]

I was wondering what ranges of voltage I should be looking for in the o2 sensors? I currently have a K@N CAI and am useing the 93 octane tune in my '03 silverado with a 5.3L. I've got the ltfts at -.78% at cruising speed, but what am I looking for at WOT? Also, does the CAI lean the mixture more? (it came with the truck) As far as the spark advance, should I increase until I see a KR reduction? Thanks for your time

You're looking for about .90 at the front 02s, but .88 to .95 should be OK.
The LTFTs should be close to 0 at WOT as well.
The CAI may lean the mixture as well.
I would not add much more spark advance as these motors do not require much timing to make good power, and it is already advanced in the tunes.

Thanks
