Eager to try the Dino Tune, but with all the parts installed as you indicated, my PP overshot to 455+ or even higher, Engine 1, racing exhaust, sport ECU, intake, sport catalytic, this goes over 450pp, with original oil, and ballast added, and power reduced. Does the anniversary edition make for more powerful cars?? lol how are you all landing at 450pp with those exact settings? Tried 2 cars. The car oversteered lots on corner entry deceleration (high speed ring) but it was super smooth all elsewhere. then my PS3 fat died ! oh the agony. luckily, I was able to get my disc out (sorry old PS3 plastic covers and screw tabs flown all over!) and get a new PS3 tomorrow.
