Well evidently everybody I've spoken to, ase mechanics gm mechanics being hooked up to 2 snap on tuners. And nobody told me there is a strategically hidden bank 2 precat. Completely blocked. Broke the flange loose on that side and fired her up and heard those four cylinders for the first time in months
Drove my truck with ease yesterday for the first time in 6 months. Felt great
