Default LT1 Running Rich - Scan Results Inside - Help

Alright the car has been getting 200 miles per tank while driving light, this is combined city and highway driving. I have no internal upgrades or anything that should be hogging more gas. I let the car get to its operating temp and wrote down all the results from the scanner :

Baro (HG) - 28.15
LT Fuel Trim - ON
LT Fuel Tr CL - 5
LT Fuel Trm L - 115
LT Fuel Trm R - 116
CC on/off sw - OFF
EVAP DUTY - 0%
EGR DUTY - 0%
Coolant - 185* (this is the hottest the car gets)
IAC Position - 29
Inj L PW - 0 MV
Inj R Pw - 0 MV
ST Fuel Trim L - 124
ST Fuel Trim R - 124
Knock Ret - 0*
Knock Sensor - 20
Loop - Closed
MAF (GR/SEC) - 8
MAP - 1.27 V
IAT (F*) - -40
O2 Right - 100-900 MV
O2 Left - 100-900 MV
Spark Advance - 19*
TPS - 0.65 V

Can anyone see something wrong here? It's been like this over a year now, A4, 3.23 gears, Ram air, MAC headers, Hooker-Catback, Air foil, TB Bypass and LT4 knock module have been done. These results were from an Actron scanner, thanks for any help!

Do you have any exhaust leaks? What shape are your o2 sensors?

Default

fix the iat sensor.
the -40*f = an open circuit.
this will cause a rich condition.
btw - if the coolant sensor does this it probably wont start!
