From what I hear, National speed doesn't have great rep. Not many locals go there. I'm trying a new shop this week to install springs & spacers. It's called Ti racing, in Castle Hayne.
There's another new shop near ilm airport, I think it's Carolina Dyno...? The guy I meet a couple weeks ago had his Nismo tuned there Sat. He seemed happy with them. They are an Uprev dealer too.
Will let you know how it goes at TI...
