very good solutions so far, I'll throw mine in the "ring". Tried a couple tunes and they did not work for me. Made my own, 1st lap 9:54, didn't need a second lap, save yourself the extra 10min and agony of driving a turd. You can find my tune by searching by GT: badad117, lap#1 9:54. This tune is power only, exactly what you need for this track. On the long hills you need to keep accelerating and/or not lose speed. Good luck.
