After I upgraded the FMIC on my EVO, it took double the time to heat soak and I could hold more boost for longer periods through out the powerband. It was awesome. Of course I was tuned for the addition of the FMIC.
I still know very little about diesels, do we have to get a reflash to maximize the effect of the FMIC?
