fast or atomic efi ?

Good! They changed it! I told them point blank "your fuel line is a joke, worst s%^T I have ever seen!" They must of gotten the hint lol! I ended up using a Walbro in-tank fuel pump too. Once the car has a few miles on it, adjust your IAC by the reading in the handheld. Basically use the idle screw to get it at 20 +/- a couple. Set it while running and warmed up.
