Wrong injector data, "MAF-only" tune with VVE untouched, and you say it acts weird on return to idle, huh? That's so weird, I can't imagine why it does that.
Anything that's 60lb at the standard 43 PSI is not going to be 84.7lb at 58 PSI.
Start with the injector data since that's the foundation all of the other calculations the ECM does are based on. Do you have a link to the actual web page for the injectors you have, or the datasheet that was sent with them? Part number?
What is your fuel system - stock, returnless? Checked that it's 58 PSI like it should be?
Couple things... First, those are not "60lb" injectors even at the standard rated 3bar/43PSI, so you had the IFR entered right, it's the part where they got called '60lb' that was off.
On the Offset vs Press vs IGNV you used the early E38 128-640kPa table, instead of the late 128-768. They have the same number of columns/rows so it pastes without throwing an error or leaving empty cells but the stuff is shifted over into the wrong columns.
IFR & Short Pulse Adder were correct, I only changed the Offset table for you. This is only a starting point, VVE needs to be tuned, MAF-only is probably not going to play nice with a cam that big.
