Not sure if this has been covered but I'm finding a few downsides to going turbo.

The 1st one and most obvious is the balance of the car. All the additional weight in the front. Especially since the JDL kit's manifold and downpipe are extremely heavy due to strength. I have come to realize this is the cost of having more power and I can live with that.

The other issue I'm having is throttle response and I believe there is a solution (tuning). Before the turbo kit, the throttle response was phenomenal, rev matching on downshifts was a breeze and precise. After the kit, the initial throttle response isn't there and I have to give way more throttle to get the rpms to rise. I've mentioned this to my tuner (HRI) and his response was that is due to the new MAP sensor.

I'm wondering if this has been the experience for many of you that have gone turbo. Please share your thoughts on how you think I can fix (if possible) this issue.. Thanks in advance.
