Your right. There is no need for TCS 1. the tunes I create at TCS 1 can be turned off and they work exactly the same, if not a little smoother in the corners. I just find it a useful aid to tune with
For sure, the sports soft tune is better than the sports hard tune but I am still happy with outcome of the 500PP tune. It makes for an easy win in a fun car. I can't recall what the paint colour is at the moment. Will have to check next time I load up the PS3.
Enjoy the Sports Soft tune. You really can drive the 550PP to the limits and it will repay you with smooth, fast driving. The 600PP version needs a little more concentration but it is very fast and extremely capable.
Edit: The paint on the Audi R8 is GT CHROME 005-C and I painted the alloys with a CHROME SILVER colour as well.
