I have constantly experimented with Teameditor, ZAZ track magic data, and GPxPatch to try and tweak my car performance vs the game's A1 cars. The mystery to me is how this differs from one track to the next. On some tracks, giving "myself" a 5% overall performance boost in Teameditor will cause me to run way too fast and run over the A1 cars while on others it makes no difference and I am way too slow. I like to adjust the settings so that I may win if I run a flawless race - no mistakes - but cannot or win not win if I do. My biggest success has been on the Valencia street circuit. On the 2008 Valencia version, I was competitive without doing anything. When I ran the 2012 Valencia version (a nice upgrade on trackside graphics), I was constantly 2-3 seconds off the pace regardless of the boost in Teameditor (which seems to not work on some tracks) until I adjusted the Magic data in Zaz Tools on that track, lowering the A1 settings slightly, resulting in my winning pole by just .2 which is perfect. Thinking I had solved this mystery for all tracks, I have since found a wide inconsistently from track to track. Any thoughts on this?
