This may seem like a simple and UN-important task, but details matter. The old engine had a very low RPM range, and low 4k red line tac. I needed a new Tachometer with a 6.5k redline, the same as the SS Camero this LS3 engine came out of, but it needs to be small, and fit the Toyota Stock dash, and have a stock look. So, Speedhut Inc mad it for us. Looks and works perfect! Just a side note, we needed to run 2 sensors for many engine management things as this dash needed to still tell us oil pressure, water temp, and more…. but the sensors that run the dash were different from the ones the LS3 computer needed to speak with. Another hurdle, but no big deal.
