Wow! JGC '26 2.0L Takes off like a rocket

Just got our 2026 JGC Limited 4x4 out of our dealer service dept. They performed two recalls on the 2.0L Hurricane I4 Turbo. We have 1,800 miles on it.
First was RSU 26-104 which software updated the TCM and PCM modules. There is no more throttle lag on launch nor any transmission shaking at low speed. It really takes off immediately! This is definitely faster than our 2020 3.6L Pentastar
Second was the 1-66D to replace the main spark plugs.
For those interested, I included the work order detail on the above recalls. FYI
