    Guys with DSC1 procharger and long tube headers. What size pulley are you running to make 5-6lbs Of boost? My truck has a custom pulley and makes 3-4. I’m installing long tubes this weekend and want to see 5-6 with the headers and new pulley.

    Thanks

    I don't have long tubes. I also have a 6.2L, but I do have a D1SC. I believe the system should be making more like 8-9 lbs. I wouldn't expect to lose 3+ lbs from headers, but I could be wrong.

    Do you have a proper tune? I would get it dyno tuned and not trust an out of the box tune.

    Your boost numbers will actually go down a bit by installing long tubes. Is your boost gauge working properly?

    Also, are you at any kind of altitude? It makes a difference.

    The current pulley is a custom pulley to run less boost. I’m looking to run 5-6 with the headers and need to know what pulley will get me there.

    What size is the pulley you are running now? If I remember correctly, the D1SC pulley is 3.4" that gets you 7-8 lbs.

    You'll lose some boost with the headers. Just curious, why are you only wanting to run 5-6 #s?
