Hi guys. Hope there are some of Si owners so wanna to show you nice thing to boost up your car.. The KTunerFlash V2 for the Si look pretty impressive, the quazi CTR may not be out of reach after all, except the hatchback requirement. I love my Si coupe, though power wise it doesn't feel 11 years better than my 8th gen Si. The extra torque is nice but top end is a snoozer (I miss 8K RPMs!). I'm just happy to finally have bluetooth and USB interfaces.
