I've only heard of one guy actually installing the GTM twin SC and it only put those type of numbers down on their dyno. Never came close to that power level anywhere else and gave him nothing but problems. He eventually threw in the towel and traded the entire car.
There are no good SC options left. Go with FI for TT and BP for single. AAM makes a decent kit but the FI is better.
