Finding Constants/Correction Factors

I want to change the intake manifold (no flaps bigger volume) on my Med17.5 2013 Audi A3 2.0 Tsi e888. I have a mappack but it has no identified maps etc that will help me with cold start running. From what I have found turning off catalyst heating would improve cold start running. I have worked my way through some of the funktiosrahmen . How do I find a constant like fhokh in my file 8P0907115BB. Are there more detailed map packs available? Where/how does one find this kind of info? Thanks for any insight.
