Yes it was tuned by PCMforless in NC

what?
i live 3 mi from pcm4less in mooresville nc.they WON'T TOUCH A LT1.....when did you get that tune?
they don't know how to tune them they turned me away twice and i walked in the office they but are all about ls tunes.
if you 383 is lt1 type and a 93 ecm how did they tune it?
is that not a that a chiped ecm?
anyway if you got a lt1 and you got it tuned at the nc pcm4less-well theres your problem.
pcm4less has another shop in ohio they do the lt1 tunes
