Review on 💡 TechSmart R76001 FICM Diesel Fuel Injector Control Module by Kevin Lawson

My shim had low voltage on FICM WOT issue. The voltage drops to 30 VDC at WOT and then slowly rises to 48 VDC. The car starts and runs well. I bought this power supply because it is made in the USA. I paid a little more for this, but I wanted quality and not cheap to buy and repair. Buy it well or buy it twice. Very happy. The tension is perfect. The truck actually runs much smoother, starts and idles great in cold weather. To be honest I had no idea how bad the truck was doing until I replaced the PSU. The difference between day and night. Very happy!
