I called Dinan today and asked about installing the cp-e FMIC/OC. The SA I spoke with said extra cooling by itself won't void the Dinan warranty. But he also said Dinan will not allow the Stage 2.5 or Stage 3 tunes with anything except the Dinan FMIC because they haven't tested anything else. So if you want FMIC for longevity, the cp-e is okay. But if you want a tune with more boost, it has to be the Dinan FMIC.
