Doing the plugs and coils in my 04 turbo cab. I run gt28r turbos with a tune. I bought the Bosch fr6ldc plugs. They come gapped at .036". I have read some people say run them at that but the factory gap is different.
Thoughts? What do you all run?
Put them in and go or re gap them?

Contact your tuner and ask him which plugs and what gap he recommends.
