Sorry but I need to sound ignorant here.

What the heck is a finger stick??? And what do I gain if I put one into my D/A, I just ordered one of the EGR plates, does the finger stick have anything to do with that???

Ignorantly yours...

Read this link here http://dieselplace.com/forum/showthread.php?t=21428 it will tell you everything you need to know.

The stick corrects the maf reading, when a free flowing exhaust and egr plate are installed on a lly engine. Without it you will throw fault codes.
My predator tells me it is working, there have been no codes since install several months ago.
