i am having some really big problem with my golf 5 gti 2006 DSG and every time i try to get my RPM to more than 2000-2100 my car would do massive cut offs and hesitate like a LOTTTT and it would feel like there is 0 power and the car sounds like you are literally trying to use anti-lag while the car is only stage 1 with an upgrades intercooler

i tried changing the sparkplugs, changed the cam-follower, fixed the air mass sensor … nothing it became a disaster

the car is literally un-drivable and the fuel efficiency is superr bad like 8km/L which is 150-160km / tank and for such a car it should be 200-220/ tank

i really dont know what i should do to fix this problem because the car is hesitating as hell

any advice ?
