Do you have a boost gauge? If the boost is down first thing to check is fuel filter. On one trip I drove all night with very low boost checked turbo hose for damage could find any thing. We stop for fuel in early am was looking at engine attendant come up and ask what we were doing told him about our problem with lack of boost. He told us to change filter luckily I alway card a couple. I changed it and were started out and instantly we had full boost.
