Thank you so much Frost!!!!
Would this also apply to a head and cam swap? What changes would be different if any? I put 706 heads on a 6.0 and also added a BTR stage 2 v2 cam.
I understand that a cam would need less fuel but I'm offsetting that with more compression, right?
OK so maybe someone can help me with this.
I have a 5.3 retrofitted in a 56 nomad.
Injectors are DW 18U-01-0042-8 42 LBS injectors.
It has a comp cams Muther Thumper cam in it. ( NOt my doing )
I have tuned cams before and never had this much of an issue.
I cant even get this thing ti fire and idle at all.
I seem to only be getting 4 cylinders to fire and it is pig rich when trying to run.
When I open the throttle to 10% or 100% this thing will not even run at all.
Since I was having an issue I thought ill go back to basics and read any docs I can. What brought me to hear.
I followed the guide but this thing wont staty running. It fires like on 4 cylinders but no go.
I have verified all cylinders coils are firing and engine has compression.
Im lost on this one, even willing to pay for some help here.
I currently have no MAF installed either so it does not get in the way.
Attached are the tune and the cranking scan.

Perhaps someone could take a look at my logs and offer any advice. I was having starting issues before I went through this process, It helped a ton!! However I still seem to have an issue where the vehicle hunts for rpm when shifting into gear. eventually it settles as long as I don't try to move. Any ideas where I went wrong?

Updated the link in Post #113. Google drive updated security policies and the original link broke.
This is the process for a DBW correct. Lots of great info in this thread. I am soaking it up like a sponge.
I haven't completely read the whole thread, but it appears the original intent of this was for a DBC, not DBW throttle body. At least that's what is posted up front by the OP.Quote:

This is EXCITING SH#@! You've got me rubbing my legs like a cricket (still in box MPVI3). Thank you for the detailed how-to.. the absolute best I've ever seen (on a forum).
