Gauge cluster malfunction

[Flxr_88]

I just put a tune on my car, stage 1+ SF 93, and took it out for a test drive. Everything was good and I let it sit for the night. I come back and the Cobb tuner fell off of the dash that I had the mount stuck to, in which broke the connector, but I’m currently working on salvaging the pieces out. I took it out for a test drive without the Cobb or cord plugged in, and when I started accelerating, the windshield wipers wiped one time, the parking brake light flashed and the abs light came on. Additionally l, the speedometer went to zero and then back to my speed. It was very finicky when I was going 35-40 and just holding a little bit of gas to keep speed up a hill, but would work fine when at higher rpm’s. It’s such a specific issue, I had no idea where to start looking. Could the Cobb be the issue? I also noticed that some of my gauges weren’t working. Boost for sure, only displaying -0.1/0.0 psi
