weird A/F readings

[tbTalonES94]

Ok i finished my conversion and if i give it full throttle and boost my A/F ratio either jumps around like open loop or goes to the last lean LED and blinks. WTF??? If im running THAT lean then something is seriously lean. Remember i am breaking the motor in so i dont rev above like 3800 and ive only WOT on the interstate at about 3 grand for like 3 seconds. Whats the deal???

Its an Air/Fuel Gauge man, Its just a disco show, mine does that crap to. Get wideband or something you can really tune with

Nah man im saying it use to act normal like when i floored it it would go to rich and stay there...Well now if i floor it it just either bounces around or goes to LEAN. This is not normal or good with a turbo car! I hace an EGT gauge it just isnt installed yet. Idk what the deal is. If my ecu is messed up or what? Also i have a god damn boost leak somewhere!
