Tuning shop?

I know this is the wrong section but I thought it would be the quickest for a response. I have a B16 with the VAFC no turbo and it’s runing way to rich (I feel like I could collect the fumes from the exhaust turn them into liquid and get another half take out of it) I think the last tune was messed up. I need a good tuning shop in South Dakota or near South Dakota. I know there used to be a list of tuning shops by states but I can’t find it. I only have the VAFC so I will have to be knowledgable about that

theres a list on H-T

does anyone have the link to the list on H-T I couldn’t find it.

Found the list thanks but i still can’t find a shop in South Dakota I thought I remembered there being one

Anyone?
