Im pretty sure there is someone over on TGO, he has 2 seperate ECMs or something, and a switch to choose between MAF and Speed Density. Speed Density from what I've read hurts performance a little bit, as much as 3 tenths in the quarter. I wouldnt bother with SD, just double check all the connectors, and if that doesnt help, go to a junkyard and yank a harness.
