I know the other sheet does not like this but give it a try, this might help you limp it to your buds shop.

And it sounds like you don't have a clue what size your injectors are, so that's going to make getting the tune even remotely close impossible and you'll never get anywhere without a wideband.

Seems this may have been useful earlier?

And+1 for knowing exactly what the injectors are. A tune without the correct info is just a guess, and more opportunity for error.

Try your old IAC and see what happens, surging could be the combo of the cam profile and a few more things. Stock TC by chance behind that motor?

You probably will want to think about a replacement later down the road. You should really have a high quality stall converter.

To the guys who have actually worked on and own a 408, thanks for your help. It runs just fine now.

Fuel sync and the new cam only pulls 14 inlbs of vacum so they turned up the idle speed just a touch.
