1G-specific Logger shows over 100% injector DC. What now?

I am in the middle of tuning my 1G and may have found a problem :eek:

My last log shows the following Injector P/W #s:
19.23mS @ 6000rpm
19.03mS @ 6500rpm
17.95mS @ 6968rpm
18.72mS @ 7062rpm
15.90mS @ 7437rpm

According to the IDC chart at http://www.taboospeedshop.com/IPW2IDC.htm my numbers are somewhere between 95%-105% on this log. Example; Taboo says 17mS @ 7000rpm = 100% and I am at 18.72mS @ 7062rpm!! At times I have even run about 1-2psi more boost than what I had during this log! Is the Pocketlogger Inj. P/W data accurate?

So, I think it is safe to say I am out of injector (550cc) at my currect 40psi base fuel pressure. Am I correct in thinking that the next step is to bump the pressure up to about 45psi at idle and try tuning/logging again? I don't want to go up to 660cc.

Thanks
