Hello all, new member and first time post.
I have a stock 2003 lb7 with a straight exhaust. This is my first duramax and I'm alot on the ignorant side of diesels. I've always thought the truck ran fine but when a friend drove it he said it's lacking in boost. He has a 2002 duramax. I'm not really wanting a hotrod but I pull a lot of trailers, large boat, etc. When driving it blows very little smoke even with load and under a hard pull u can very lightly here turbo, like pulling the boat up the ramp.
So I was wondering if there were simple things to check or is it time to take it to a certified mechanic? Thanks
