Look at short- and long-term fuel trims on a scanner to see if they're within reason.

I did not fix the speedo. How do you do that?

I got 14.5 the last tank. I may have been letting it warm up more than I realized.

My fuel pump died. Replaced it. Truck is 2x as fast now and I think may have been the issue the whole time. Could never accelerate over 3k. Lol I’m an idiot.
