Hi. I got my car remapped six months ago and it was then doing 80-120 km/h in 4. and 6. gear in 4.5 sec and 7.2 sec. Haven't noticed any changes over these few months, but when I tried this again this weekend I was suprised to see that it took me 5.1 sec and 8.2 sec. The only thing I have done with the car since then is changing to a Forge resirc. valve. I noticed that it took an hour or so to adjust after changing it, the car was hesitating a bit at full throttle especially in 4-5-6 gear. What could this be? The car feels fine and has had a service and change og airfilter in august...
