What changes are necessary for my 85mm Slp MAF and the 90/90 fast combo in my pcm in my VCM with my HP tuners,i am sure there is a significant effective airflow change with both!

yes..you will have a pretty good amount of change..
you shoudl tune using AFR error % and redo your VE and MAF tables for your new parts

i am really new to tuning with HP tuners but getting the hang of it this combination is very new so there are so many things changed that i am kind of in the dark im not asking for someone to do it,just to be pointed in a direction so i can learn where should i change the info.i saw on one post to select effective airflow and multiply by 1.48 but that is to vague and i will not do that!

effective area has nothing to do with your new mods..
The Effective are has to do with the IAC motor....if you changed to a different IAC motor..then you would need to change it..otherwise.leave effective area alone...

make sure you drill a hole in the 90m TB as your car needs teh hole to idle properly(same size that was on your stock TB at a minimum)
you are not going to get enough air through the IAC with your mods
