Astra h 1.9 cdti 120cv lazy, can someone help me with stage 1?

[davidbcn]

Good afternoon, I would like to try a stage 1 for this vehicle since the car feels very lazy. Original file attached.


I also have problems with cold start and I don't know if there is any solution in this regard. I thank this forum in advance for all the unconditional help provided.
