Fuel trims!

Fuel trims!
Alright I've had a nightmare of a time trying to figure out why my truck has intermittent fits of "I feel like having the power of a 2L today"
Ran a compression test a while back, all are within 20 percent of each other except number 2, it was at 140 psi. Average for the rest were 165.
Trucks got 284,000 miles on it, the picture of the fuel trims under 10 percent is at idle, the other is at 2000 rpm no load. I've got exhaust leaks on cylinders 7 and 8 due to broken header bolts.
Do the trims show I've got another air leak? Like for the booster.
