POWERHOUSE now stocks FMU recalibration kits for not only the standard early FMUs, but also for BEGI's new "shimless" FMU. For those who do not know, a recalibration kit changes the rate of gain in your FMU when you do not want your fuel pressure going as high as 100 pounds or more. We commonly use these when big injectors are involved - these kits are perfect when you are trying to make injectors as high as 65 pounds work in a Gen 1. At full boost with a recalibrated FMU, you will typically see slightly above 70 pounds of fuel pressure. Call us directly with your application, and we will be happy to let you know if one of these recal kits will work for you . . .
