i have to say Unleashed/Torrie is top notch when it comes to service and response time. I only wish he explained what he changed and why on each revision, instead of having to notice it myself in the datalogs. I also have to say, try an E30 tune if possible but be prepared to point and shoot the BULL wherever you want, and your tires will hate you. I almost bought a Flex twice before getting a SHO instead. Now I have my sights set on the 2020 Explorer ST.
