Just had my FICM tuned by Josh at Darkhorse Diesel. I already have SCT with Innovative Diesel Extreme Street installed. I immediately noticed better throttle response and more power. Worth every penny. Seems like the RMPs stay higher between shifts also. Like Josh said, it makes the Extreme Street feel like Extreme Race and Race feel like X. Also saw about a two mpg fuel for the short time I have driven it.
FICM tuned!!
