Just had my 159 2.4 qtronic remapped/dpf removed by AHM today, nice guys, a 160 mile round trip. But I seem to have an issue where I hardly feel any difference in the car, only difference is around the 70-90 mph where it feels a little quicker.
If im in 6th in the 1500-2000 rev range and floor it, it will judder back and forth and feel like it is holding back until it goes over 2000. Same in the lower gears sometimes, it just feels flat. There are so many great reviews and happy customers from AHM saying that it transformed their car, but mine just feels the same as it was before I went up there. I can only assume that ive got a problem somewhere, it just does not at all feel like a 240 bhp car.
Could fuel be an issue? I had millers in the tank AND shell nitro+ whatever its called.
In low gear changes (since i had the car) I get a long whoosh wastegatey sort of noise. as i understand, these motors dont have wastegates?
Im just abit stumped, and a little deflated. Its been a long day getting there and back, and it was expensive
If anyone might have a clue, please give me a slap
thank you in advance
