Power Logger Runs....?

[V8killR4U]

I dont know how to zip the files, to post on here, can you fellas help me out and take a look at this post on the FullThrottle site and provide some input...

Im having a tuff time.

Ive been fighting fueling issues with my car for quite some time now and am starting from square one. Car always seemed to fall on its face and knock on the big end (Past the 1/8 mile). I always thought my fuel system was up to par...maybe its not. I have a new XP pump, 75 inj, and dual alchy.

What do you guys see. This is on straight 93 Octane no alchy. I thought the boost was set at 15lbs but it got up to around 18-20 lbs.
I have Erics TT SD chip an could set A/F but i think my Sensor is shot. (I just bought it too) Take a look at my runs especially the 02's and duty cycle and let me know what you think. Looks like the O2's should be a little more consistant...I still think i have a fueling issue some where.

What do you guys think?

It appears to me (assuming the wideband is correct) that you don't have enough fuel volume as you get up into boost. I would put a fuel pressure gauge on it, and monitor pressure under boost.

The stock O2 is not reading correctly. What kind of O2 are you using?

Also, idle is a little rich. I would drop the idle fuel by 1 number and see how that does.
