GTP Runs too lean

[turk182]

I have a 98 gtp. I put a large cone filter at the end of a short 3.5" aluminum 45% tube the filter is the biggest I could find (for a truck) its high flow with the screen in the TB reads no codes once I took out the screen it reeds a Fuel mixture to lean code,how can I get it to push a good Ratio out or can I hot wire it to run a better fuel air ratio.

put the screen back in... there is no reason to take it out... it straightens out the air flow which allows the maf sensor to function correctly
