P1131 Lack Of HO2S11 Switch - Sensor Indicates Lean

P1151 Lack Of HO2S21 Switch - Sensor Indicates Lean

you front O2 sensors say you are running lean on both banks. from the looks of you mods you are running lean. you need more fuel in the motor.

well the safest way to fix it is to get a dyno tune. i can only tell you prices from my area, which are around $175 to strap it down and $150 an hour after that.
