if you only change ignition timing post start, will be louder but not like stock

stock cold start is very loud also because has higher idle so if you want it loud rise it like at 1400 rpm minimum, on the "left" zones of the idle maps

v4 tunes has max of 1200rpm that s not much to get it loud


but yes, it s basically only that, try put -15 or -19 (this one is on my17+ stock rom) and hear it



but v4 has maf correction after start a lot reduced on cold start, you should put higher values on the first 2 rows in those 2 maps, but v4 oft definitions have them not defined, you need better definitions to modify them
