LT1 Edit open loop program ...a couple qwik questions

Just thought I would throw this up here and see what I get from it . While the part throttle programming for my car is about dead on , at WOT my car is really rich . I have been trying to tune the car at the strip , but all the changes Im making the car is just getting richer . I want to make sure the areas Im tuning in are where I need to be . At first since with the base program the car was pretty rich ( 950-1000 mV all the way down ) . I figured I would try to lean it out with PE table and leave the VE tables alone . I got down to where the PE table was 0'ed out completely and from 6K to 6800 I was actually going into negative values . Doing that , there was no changes in the way the car ran . 02's were still .950-1000 mV . Then I figured I need to go into the VE tables . I was tuning between 90-100 kpa . The more I subtracted off the value in the VE tables the richer the car got going down the track . 02 mV's are now 1050-1100 area , blowing black smoke all the way down the track . Since that day , I blew up the transmission and got cut short trying to tune this thing and decided to call it a year.

In an open loop program :

-do the PE tables have any effect on WOT ?

-Am I right by subtracting values in the VE tables to lean the car
out ? A friend of mine told me that he thinks the values
represented in the VE tables are telling the PCM how efficient
the engine is , he wasnt 100% sure though . If that is true
I assume I should be adding to the values to tell the PCM
the engine is more effiecient so It would add less fuel .....
....yeah , nay ?

I did not have the opportunity to play with injector size before my tranny ate itself . I know I probably coulda made progress there , well @ WOT anyway . That surely woulda threw off my GOOD part throttle tuning . I still have stock 24 lb/hr injectors , so I know as fact with my heads cam combo I surely dont have too much injector .

It would be very cool if someone could clear up the questions I have:)

a1. yes, the PE tables are used in open loop (I run an OL program). If you've got your part throttle stuff set up, you should only need to change the PE/RPM table.

a2. yes, that would work, (assuming you changed the correct area) but only in speed density mode. Does your car have a MAF? If so, the VE tables are not used.

BTW, I wouldn't pay too much attention to the factory O2 sensors. Also, dyno tuning is critical to figuring out how much fuel the engine likes at a particular RPM, my PE/RPM table ranges from +16 around 4000 to -15 around 6500.
