Default error code 45 after installing turbo

I just installed my kit today... my check engine light came on when i was driving down the road not boosting... its #45 which is "system too rich or too lean"...

Im currently running a FMU, walbro 255, and stock injectors on a 2000 ex... boosting about 6 psi right now... i have an exhaust temp gauge, which seems to be reading good, however i dont have an A/F gauge just cuz they are more of a light show than a functional gauge... do you guys think my **** is too rich or too lean?

well i took out my silencer for my buddy club spec 2 exhaust and reset the ecu and now its fine!!

i guess my silencer was restricting my exhaust flow, therefore building up lots of gases in my exhaust...
