SCORE–TROPHY TRUCK
EFI offers two different engine control systems for offroad racing; the X3 ECU is ideal for Class 1 and the Race X5 ECU is the ultimate system for Trophy trucks. The Race X5 ECU is the system of choice of Shaver Specialties who prepares the engines for Collins Motorsports and Mulit time score championship winners Terrible Herbst.

"EFI Systems generate more horsepower, are more reliable, and are easier to use than any other system on the market. If you want to win, go with EFI!" – Ron Shaver, Shaver Specialties

Terrible Herbst uses the Offroad Logger System to gather vital data to improve engine, transmission and suspension performance. Data from any temperature, pressure, strain gauge, or drive shaft speed sensor is logged at up to 1000 times a second to catch every movement over the harsh terrain.
