I know the factory governor kicks in at 136 MPH if I am not mistaken. I also know you can remove that restriction with an ECU flash. Just curious what is the highest speed you have lets say heard of an Si with a 1.5T go and with what mods and tunes? I am just wondering what the upper speed limit you could get out of a 1.5T with reasonable modding. Obviously at some point the gearing is going to limit the top speed maybe even before the engine would but I know the gear box will take it past 136.
