Default somewhat rough idle / log'd missfires

ive had a somewhat rough idle with the s4 from day one before the mods, before and after timing belt swap, this is what i logged, can you guys tell me if these are acceptable counts for idle? or if not what i should maybe look into checking next? thanks

i searched the forums but came up without any answers

with about 1-4 counts on 14 but very slow counts otherwise at 0

also 1-2 counts on 16 but slow coming up as well

do these sound normal? or should i try swapping plugs or something?

oh and this is at full idle 790-800
is there anyway to raise idle? i tried but got a error that i couldnt change the values
thanks

Default 4 total misfires shown in block 014 of VAG and 2 of those on bank 2 (block 016 in VAG)??

4 total misfires is nothing, surprised you can even feel them.
