Hello, I'm hoping someone can help me with this. I'm really green on gas tuning, diesel is more on my wavelength. Anyway, I have a 2017 Buick Regal 2.0 T LTG. It has an aftermarket intake, and it seems the intake is causing a false lean condition. My fuel trims go high most of the time, but the exhaust smells rich, and my cat started setting an efficiency code, presumably from overheating.

Can someone tell me which tables to adjust to correct this? I messed with the VE tables a little, but it only seemed worse. Thanks in advance.
