If the map was changed, there is no way to tell how much it really gained.
I just fitted ITG intake after having carbon speed. And by logging 3rd gear acceleration with Racechrono sw and GPS before & after, the difference is very very small on the road. Maybe the car needs to adapt or something but so far Im a bit disappointed. And I dont care what it makes on a dyno, its how well it goes on the road that counts.. That was also the seat of the pants feel after fitting, just confirmed with timing.
I would be interested if anyone has made acceleration measurements with GPS for example from 100-160 or similar, before and after the fitting of ITG? Try for example the free S60 application
