Turbosmart Hypergate 45MM on the housing

3IN Turbo back exhaust a 5in Cat body, with 2 mufflers and a twin tip end.

Im using a boost tee as my electronic controller from insight motorsport shit it self after a week. The boost is pretty jumpy you can see it in the power curve I actually hate boost tees after seeing the difference.

Made 368rwhp on 16psi using caltex 98, however manifold keeps making a massive exhaust leak so I'm going to take it off and check/machine flat and then get it back onto the dyno to run more boost and make this turbo come alive.
