I am not sure where I should post this because it could be fuel or ignition.

The last two times I drove the car I experience this. A miss/stumble after a shift. I never experienced this before.

One odd thing I noticed (that you can see in the first video) is that the tachometer takes off at higher RPM. I had never seen that before. I also don't believe the tach. That was not a 6K shift, it may be my imagination but I feel power is down. The second video was after I filled up the gas tank. The engine does have a ground strap it is mounted to a bell housing bolt. I am going to add a second, probably to the block. I have the parts to do that.

Early on I had a similar miss and I upped the rev limiter to 7,000. I assumed the dial MSD was inaccurate and I had "fixed it" I was going to start dialing it back until I hit the limit and bump it up again.
