I got a 2021 Focus ST 2.3 ecoboost, tuned to 356Inked357WHP_LI.jpg.8WHP with intake, downpipe, intercooler, and exhaust.
But when I test 100-200KM, there is a small problem puzzled me for a long time. when the car changes to gear 5 and the speed reaches 180km/h, the airmass will drop to 250-260g/s from 330g/s. So the car could not get into 10s for 100-200
I attached the datalog. Anyone could give me some suggestions
