Dude... I've sat in the god-car Myvi 1.5 manual up Ulu Yam roads and I've personally experienced how fast a "slow car" can be under the management of a fast driver. It's not the car - it's the driver. Then there was the time a certain Pikachu out paced a Lambo up the same roads.
I've given up on ego/pride. As long as the car in front of me isn't being a dumbass I don't care what's in front of me or what overtakes me. I only take offense to those driving slower than me hogging roads.
@Ranjanmax if I'm not mistaken the re-map done by a shop will cost about 2800 give or take. Freelancers can do it cheaper maybe 2k and below.
On a separate note I know a guy who has the VW ECU software and he enabled a lot of switched-off features on his Jetta using the software as he bought the lowest spec model. All they do is disable the features on the lower end model most of the time which is cool since he upgraded to the top spec free.
