Ok, did the settings last night holy mary mother of god! it was insane, Now what about full throttle? I am more tempted to use half throttle from here on out, should I go back 10% or what does everyone think? Thanks guys for the help.

At-a-boy! I just hope some of the assclowns on this site that question my every word, read this post and realize, that "Hey, perhaps Stazi does know what he is talking about". Ah, fuug 'em

For you WOT settings, it's hard to tell sitting behind this computer and all and not riding in the car and seeing it for my self.

I assume you did the blue wire mod right? You frikkin' better have or I am gonna sap you. Anyway. Do some 3rd gear pulls with the "Sensor Check" menu up and watch the #2 input voltage. That's the O2 voltage. What you'll want to do is do a number off runs, from 3000 up and watch the voltages (helps to have someoe you trust to drive the car and YOU watch the voltage). Concentrate on 1000rpm bands at a time (so as not to confuse yourself). Start with 3000-4000 and work up to 4000-5000 and on to redline etc. adding or subtracting fuel at those rpm points in the HI setting a little at a time and watch what happens. You want to aim for around 0.91-0.92V (roughly). Make sure the driver is NAILING the pedal otherwise it'll be off.

In this instance a datalogger, like a laptop with OBD2 scanninfg software would help as you could simply do a run recording O2 voltages against rpm and then looking at the graph afterwards and add/subtract fuel as required. Then do another run and check again.
