I have a an A3 TDI 140 PD and I'm thinking about getting an FMIC kit. I've seen shops advertising up to 30kw gains over the standard IC. I've heard though, that the standard IC is plenty good enough to remove the heat fom the standard turbo, and therefor you won't see any gains from a bigger IC.
Surely the greater heat reduction from a bigger IC will result in cooler air in the inlet manifold and more power ? or would this only be noticable after a remap?
do Diesel turbo/IC systems work any different from Petrol? (sorry if that's a dumb question)
