Don't forget to perform a Phonic wheel reset, using
MES, as you had the timing belt down.
I think Self-adaptation reset would help, too. Just 'Execute' them both and the new parameters would set afterwards.
Check the 'Spark advance reduction', that will tell you if you got the timing it right. When timing is right, SAR is zero. If SAR is on positive value means camshaft is forward, if it's on negative value, camshaft is backward.
