Well, after much research, procrastinating and mind changing, I bit the bullet and got her Dynotuned yesterday. Decided against the CAI due to their reduced filtering ability, spewin coz I'd love to release all those beautiful turbo and induction noises, but she sees a few dirt roads and nothing filters like the OEM paper filter, so stock airbox remains. The only other mod that could help the tune is my Q300 catback which I fitted myself years ago, so no parts added, just a straight tune. Got it done at HorsePower Factory in Dandenong South, cost was $1295.
Stock HP for our 2Ltrs is 268HP of which about 187 of them reach the wheels. After remap is 292.7HP at the flywheel, 204.89atw. Torque was increased by 11-25% across the rev range, From 350Nm torque to approx 437Nm at peak, 395Nm average. But more importantly than numbers is the lines with no dips.
So what difference has it made? Smoother Idle, much improved throttle response, builds boost earlier, quicker to start moving from dead stop, no flat spots or drop offs in acceleration. Obviously early days as it was just done yesterday, but happy with the noticeable results. Will test 0-100 time with the Draggy soon, see if its made much difference to the 6.7sec I got out of her so far.
