GE 9FA DLN2.6 liquid fuel operation

Dear all
On site we made an upgrade from GT GE 9FA.03 DLN 2.0 to 9FA.04 DLN 2.6 with AGP and MARK VIe
Do you know what are the expected output of this machine , before the upgrade we knew that we could reach with liquid fuel during 270 MW at 588 dec C exhaust
After the upgrade we almost reach 222 me with 540 deg C of exhaust
We have also serious problems of eunnkng the water injection since it brings dynamics pk4
Can you please advise ?
