Under Fuel, set Injector_Skew_Percent to 125 for winter or 130 for summer. I set mine for 127.5.
To get deeper into the IFR non-issue, DHP's IFR table is for "milliseconds per gram" so theoretically you'd lower the numbers with bigger injectors because it would take LESS milliseconds to spray one gram of fuel. And there is for sure a number of people here that LOWERing the mSec/Gram worked like it should. Not sure if DHP version makes a difference or anything.
