Monitoring your diesel engine’s RPM is critical whether you’re towing, hauling heavy loads, fine tuning performance upgrades, or simply daily driving. The ISSPRO tachometer provides precise, real time engine speed data that your factory dashboard may be missing. By knowing exactly where your engine is operating within its power band, you can shift more efficiently, maintain optimal torque, reduce unnecessary engine strain, and protect critical components from over revving.

IMPORTANT NOTES:

• 92 And Above Option gauge is sold with a bracket, wiring harness, and R8913 filter which allows you tie the tach into the 92 and above Dodge ECM
