That is correct. Original IQ is not going above 60,9 mm3 so this values in original map is not important.
But when tuning and increasing IQ over 60,9 mm3 and increasing pressure to 1400 or 1450 bar..than it affects.
And it looks to me that value for 70mm3 and 1400bar is wrong and needs to be corrected. So question is...what is right value for 70mm3 and 1400bar? I requested 1450 bar for 65mm3 and more over 3000RPM to achieve good EOI without too much advancing injection.

i think its more than 1400 because normally you have max 1350bar and maybe on wot you have peak boost, maybe peak railpressure as well, than you have a peak boost with some more fuel a short time. which is more power. or not:) just an idea
