When I started looking into chipping mine, Hypertech was the first company I contacted. They told me that because of the low numbers of Crossfires that they had no plans to develope a programmer for it anytime soon.... That was back in Dec. or Jan. .... Power Chip and Upsolute were the only 2 that were chipping Crossfire ate the time because they also did SLKs. Hypertech doesn't do the SLK either.
