Motor is burning oil, and is slow lol. So there is a possibility. Compression test showed ~160 on all cylinders.

Edit, may be leaking oil too, but I cannot find from where.

 

That's pretty good compression, so the issue probably lies elsewhere. How is your PCV set up?

 

980ohms!! Time for some plug wires, I had a few that ohmed that high and my truck would break up under boost. Swapped to some that ohmed around 450 and it fixed the problem.

 

Crankcase ventilation is just the valve covers teed together, and a breather on the oil fill cap. Both ports on the intake are blocked off.

Really think this could be an issue? Any other opinions on this?

 

where in the tune did you add timing? main table, idle tables? and how far down on the table did you add it? more timing isn't always better but for cam tuning you usually add timing until vacuum smoothed out then drive and pull some out if need be. but you cant just add it to where its idling at. you have to smooth it down the map and to the side. also your idle in park and in gear tables need to almost match if not match your main timing table. if not the its going to do one thing at idle and another soon as you hit the gas. that will cause bucking also. i've had a issue with the raf table before like that but its been so long ago i can't remember what the issue was.

try cleaning the idle air control motor.

 

in the video timing looked super low and bouncy. when you raised timing it was all over the place. your wide band also looked like it went lean a few times. sudden lean spikes like that will make it buck like a ****. i have one little special spot on mine that if it hit that one spot it would buck and do all kinds of craziness. richened it up in that one spot and it was good.

 

I found that too, the more time I added the more vacuum the engine made, it never stopped making more vacuum... I got up pretty high with the timing too, like mid 30's. So setting the idle timing to max vacuum is not exactly correct. With higher timing the timing seemed to bounce around more, but it audibly idled smoother. I pulled it back to 21-24, forgot which exactly, from my tuner's recommendation.

 

There are tables that keep your idle within a given RPM. You might want to zero out those tables to see if it elimates that effect.

 

my idle jumps around 14-25° is that normal??? I have is set to 21

 

Mine does too, that's how it maintains the idle speed.
