Save yourself money and check your turbos pressure for leaks! Loss of power, poor miles per gallon and deteriorating performance are signs of losing boost pressure. This tester is designed specifically for trucks with 4" turbochargers and is made to restore your full potential of your trucks power. A turbocharger that has a boost leak for an extended period of time will fail prematurely. This important preventative maintenance check can save you a break down while hauling a load.
The turbo boost leak tester tests the complete intake system with your engine off. You can apply maximum boost pressure (10-15psi) and listen for any air leaks. When applying the pressure to this tester through compressed air, it will force air in every part that the turbocharger would normally pressurize.
