Kegger mod is cutting down the runners inside the plenum a bit, and opening up the injector holes some, to 'unshroud' them, sorta. Shortening the runners improves flow some, but, also moves the power band up a little bit. (only a couple hundred RPM, if that)

I modded my kegger, and I rather like the way the engine runs now. But, mine was seriously blown, so, I don't know just how much of an effect it had, as compared to stock, cause it ran like crap when I bought it.

 

i used a poor choice of words.. I said plenum mod which would sure seem like i was meaning keg mod, but I was talking about addressing the weak plenum issue by replacing the belly pan with a thicker aluminum plate such as the Hughes..

my bad.. sorry.. i'll flog my dog with a chain for my transgression.. :-)
