Ok guys great news after messing with it for a couple hours I finally got it to run. I had to keep giving it gas. It will not idle. I am also guessing this is because its a B cam. I herd they idle a little rougher then some of the other ABC cams. I turned the idle up a little and it seemed to idle a little better. I didn't want to just keep turning it up. Maybe since the ECU is new it has to learn how the vehicle works. Sounds great though!! I don't have time to do anything else to it today but I am happy I finally got it to start. Now that it is running but won't idle what should I try doing?

+1 on the MAF seems to be a given with those kinds of mods

physicaly rotate the tube. the air in the tube can be moving differently, so sometimes there are different parts of the column of air the maf likes better.

^^ you can skip step 1 since you have a new IAC.....Another dumb question but are you sure you mass air is calibrated for the 24# ers?
