working on some fuel info to help those with the turbos and the fuel issues. Hopefully we can figure out a way to handle any amount of power :)

Hey Travis, do your excellent sources have the part number for the HP fuel pump? I'm wondering if the kit they put in the Cobalts will work for us.

Don't know. I've got a friend who has a kit for his HP pump (Mazda Speed 3) and he told me last night that the same company does a kit for the Cobalts. He's supposed to send me contact information and I was going to send them our part number to see if they could tell if one of thier kits would work.
