but initially the aim was for better performance. I was very impressed with a few of the installs I saw here and tried to use them as my guide. I've put about 500kms since the install and the butt dyno has noticed a difference. Although subtle, it feels the the turbo's spool a bit sooner now. I don't notice the same "BANG" kick in the pants like I used to with the DoolZ at a certain rpm. Instead, it feels like the torque curve feels a little more linear if all of that makes any sense.
