Is not that bad changing over as your just changing out the load cell, foot valve and data channel cables. The base setup of the 902 you already have is in place. It’s like rewiring your car, but not that hard. Maybe a day to install. The full package from Yourdyno was like 12k for what we wanted, we wanted 12 EGT, room temp, air pressure/water grains, water/ oil in-out temp/pressures, fuel pressure / temp and flow, turbo boost etc, he can customize for what data you want to collect.
