Engine/Transmission (1994 - 1998) Anyone have a tuning guide for the p7100

[LVJUNIOR]

I am getting frustrated trying to tune my truck. Does anyone have a guide that shows what adjustments do what. For example how do I tune the pre-boost fuel, idle fuel, top end fueling, cruising fueling, and how to tune for spool up without making a smoke show.



I moved my AFC back 1/16" and the bottom end fell on its face bad. Is it normal for such a small adjustment to have such a dramatic affect

 

[champspa]

yes , I usually move it about . 015 at a time , this amount will make a big difference in smoke on mine. it seems to be a fine line

 

[LVJUNIOR]

How do you measure the . 015 that is only 1/64". I can't see a good way to get a caliper down there.

 

[champspa]

I know I measured mine with adjustable parallels.

I am trying to get my low end power back with out creating a smoke show. Any ideas?

 

[champspa]

I looked at your signature and didn't see any gov springs so maybe it's the cam . gov springs usually move the power up the rpm scale.

 

[LVJUNIOR]

Yes I have 3200 gov springs. I can get the power down low I just can't seem to do it without a large black cloud. If I clean the smoke just enough to avoid a ticket My turbo lags until 1700rpm. If I send smoke signals to space I get boost as soon as I leave the light
