Now, when I have an M2 with, as far as I can tell, minimal lag I really don't want to introduce ANY lag but I'm really interested in getting the temps down.

To be honest, I will only drive on the street and rarely pushes the car to the max. If IŽd ever track I really don't care about more power because I don't have the skills to push the car I'd reckon.. Maayybe in the future I'd possibly to a stage 1 tune but that's it.

But if I where to upgrade the FMIC and want NO lag, could you guys with experience back up that there is no more lag with, for example, a VRSF/CSF/Wagner 5" than with the stock FMIC? I mean, I'd almost rather skip upgrading at all than risking the introduction of noticable lag. And with noticable I mean measurable in tenths of seconds on a 0-100 km/h time.
You should not notice any lag with a quality 5" intercooler.

VRSF, Active Autowerke, Wagner EVO I

CSF is a 6" not the best option for a stock car
