IFR limits for Gen III PCMs?

[DrX]

I spoke with someone who assumed that my IFR table was scaled simply because I have 95lb/1000cc injectors. As far as I am aware there is effectively no IFR limit as the EFILive upper limit shows 4063.4985 lb/hr for my OS. There are other reasons why I need scaling, but I was not aware of any hard limit for IFR with a Gen III PCM. Is this correct?

GM don't have hard limits for everything, in the case of the early E38's the problem is the scaling GM used allows for very small adjustments, but limits how big of a number you can end up with. From memory the LS1 can have a pretty big number with the limitation being the maths behind it.
