Lean under WOT.

Lean under WOT.
When I take off, my car goes very lean. It was mentioned I may have a vacume tube on wrong, or missing. I removed the emmisions, and did the TB mod. I also did the Fuel Pump Relay Mod.
If I hooked up the wires on the Fuel Relay mod backwards, could this affect my fuel delivery under wot?

PLayed with it at lunch, so here is a fresh update. I can get it to idle around 850- 900rpm. Little sputters. When I throw it into gear, that is when the real bucking starts.
My wideband reads 11.1-14.1 when in idle, and in gear it goes from 16.1-20.1+. Aren't those lean numbers? The wideband is new to me. I have calibrated it a couple times, same readings.

Would a vacume leak cause you to run lean?

what dose that all mean? i'm trying to find out what's wrong with my 13bt and someone said my FCD may be trying to save my motor and thats why I'm hesatating but how do you tell if your lean and all that?

Well, I found a leak under my bac between the UIM and the LIM. I could not hear it, but with a can of carb cleaner, and that little straw, i can hit it just right. I have already removed them, put new gasket on, and used the best sealer I could buy. No luck, still sucking air. So, I will try my other UIM and LIM.
Warped? Cracked?
hell, not sure.
