You can get one directly from Holtzman engineering or from most other Aftermarket performance supply houses like SLP, etc. Also at least in Alaska most dealerships carry them. I just ordered today the new holtzman ATACC system for my 800 RMK. It is basically a tempa-flow which incorporates and automatic altitude adjustment. I ordered mine from Fett Brothers Performance out of MN because Holtzman was backordered tell January. The people at Fett Brothers were super helpful and had the ATACC in stock I also Know that they carry the Tempa-Flows along with other nice products. Their PH# is 218-334-3388 give them a call and they will hook you up.
