Big Bad ....You are correct ..... I have always found to do it infront of the maf to change the fuel delivery... BUT to close will freeze or to much of a shot will freeze the sensor/.

You can run it dry after the maf just have to sit on the dyno for an hr or so to make sure its running a lil rich THe only thing I would say to get No matter what would be a fuel pressure regualtor with gauge and A fuel pump Would be another.
