I just installed my new stage one injectors last week and I have a couple of questions. First is that it idles fast anytime I drive it. Usually on a cold start up it idles at normal rpm but after it has been driven it is idling at high idle speed. Any ideas what could be causing this? Also when driving it it doesnt run real smooth. The last thing is that it smokes pretty good at an idle, worse than my old injectors did. Is this normal? I do have 250 miles on the new injectors now so I would think everything would be settled back in, but then again maybe not.

2000 F-350
175k miles
BD Chip (Need to get it reburned)
5" Exhaust
6637 Filter
Stock Turbo

 

If the tuning if for split-shots from the 2000, than it will run like crap until the tuning is for single shots. IMO it should be parked until the right tuning is on it.

 

have you driven it hard yet? if not, drive it like you stole it.

 

Agreed. The tuning needs to be for the new single shots otherwise your going to have issues.

 

Thanks, thats what I was thinking. Chip needs new tunes for the single shots then. Makes sense to me.
