Carboy. They do great work, but they're extremely pushy on selling stuff. Even if I got out of there with $500 on the remap, I'd end up with at least $250 in "must-have" accessories. A $1000 rebuild I had them do for me (tear down the engine and rebuild it back to check out some weird sounds I have coming from the block) turned into $5000 almost overnight.
I've got my stock ecm and map sensor back in now, and except for the stupid CEL when I hit positive pressure, its running fine. After checking some stuff out, I don't expect there to be tooo much trouble with the new engine and add-ons.
