lly fpr small lope?
 

my truck has a small lope nothing major you really cant tell it in the rpms but it is a small sorta fast lope maybe at a 1 sec interval between each one. but it only does it in drive while its under a load i guess is the only time it triggers it, never in park though. there have been very few times you could see the rpms jump and they were very little mabe 50-75rpms i was thinking possibly the fpr is going out that seems to be a common problem with these llys
this truck is bone stock 60,000 miles any help? :argh:

we have changed a couple of the regs on the llys for similar problems, if you have a way to watch the rail press you can tell, should see the actual bouncing higher then the desired

There were some calibration updates on the LLY for this. Might want to check with the dealer or get someone with EFI Live to take a look.

thanks guys i was just hoping this was no major issue im new to the diesel world ive had gassers all my life:dang: but it dosent seem to hurt the perfomance any to me i have a buddy with a edge where i can monitor my rail pressure when i get to that ill post the recorded pressures im not to sure what numbers i need to be looking for on there
