P0172

[AlanSpeed3]

Hi, If anyone could help I'd appreciate it. I have a 13 Speed3 fully modded that is throwing a P0172 code. Lt and St trims are full negative at idle pulling back fuel. I can drive for 300 miles without a light, as long as I don't sit at a stop for more that 40 seconds. I have cleaned the MAF and throttle body, changed plugs,air filter, WB A/F sensor and O2 sensor, cleaned the injectors, pressure tested the induction system from MAF outlet the the intake manifold, changed otc maps from Stage 1, 2 and 3 and removed access port completely to revert back to factory software. I have also modified the throttle inlet snorkel to accept the MAF directly to eliminate the boost system completely. (I thought of this after Cobb T.S. insisted that i have a post cat leak) All these test and procedures still result in high negative trims at idle and a P0172 within 2 minutes of idling. Also, with my Autel scantool hooked up at cold start, all pids seem to be normal for the first 5 minutes of running time, with no cel setting. At around 5 minutes and 160 f. the Equivalency ratio, A/F ratio and fuel go full rich. I have included data logs. Thank you for your help.
