Hi All I have now had the opportunity to put about 850ks in varying conditions on my T, recently enhanced with APS Phase 2 with valve spring and auto upgrades. My thoughts todate ..........wooooohoo , the vehicle has been transformed without losing any everday driveability in either traffic or on the highway. The beast now squirms for traction off the line all the way through first gear, second gear now finally has some potent power even from low down, and overtaking is a breeze in top gear.(note 2 self traction control on in the wet ) Simply put there is a heap more torque and the power delivery is very linear, comes on fast and feels very very strong right the way through the rev range in every gear , blew me away just how quickly the speed builds. Noticeably more so after purging the beast of BP Ultimate and running through a tank or so of Optimax, throttle response is more positive and power delivery is crisper .......go figure cant believe fuel would make that much difference. The Zorst has a slightly deeper and meatier note than standard and sounds a treat when under load.Gotta love the burble when backing off. Gear changes seem to be snappier post the auto upgrade, but durability will depend on how I treat the box , time will tell. My genuine thanks go to Peter and his team at APS in Melbourne for their attention to myself and my T, in my experience a new benchmark in customer service. This not an APS advertorial , just sharing MY impressions with other forum members. PS , can only wonder about the joys of Phase 3 Cheers WhiteTee
