1987 Japanese truck.... that'll most likely be carbureted rather than
fuel injected. And they tended to use Mikuni carbs, which are
notoriously ill-tempered as they age. Power loss at speed coupled with
getting worse when turning one direction and better in the other sounds
like a fuel delivery problem- stuck float valve, plugged fuel filter, etc.
