Just exchange ECU with me if you want, and get your speed cut issue solved. You also get improve rev to 7600 (normally 7000) and better throttle respond. Don't worry, N1 did for me.

What cwf said is true, unless you want to go for major mod, which able to cost you over 50K, otherwise go to reflashed ECU, you can feel the improvement.
For Fcon Vpro, I would like to add a bit info; Only HKS certified tuner can do tuning, and I believe very few of them in Malaysia, and I believe none in Penang.
