If you're wondering whether or not you shouldbuy an actuator to compliment your Stealth turbo, allow us to share our thoughts. The L5P actuator has a very low failure rate in the field. The fact that it's well cooled and not in close proximity to the hot parts of the turbo means that it's out of harm's way. Unless you're experiencing codes that indicate actuator issues or know for a fact that your actuator is somehow damaged, we would suggest saving your money and retaining your factory actuator. Add on a Stealth Boost Tester. Boost leaks can kill diesel engines. They cause higher EGTs, decrease your power, and lower fuel economy. Properly being able to test your entire charged air system is essential to getting peak performance and longevity out of your diesel engine. Charged air systems include everywhere from the turbocharger to the intake manifold. Your intercooler system, Exhaust Gas Recirculation components, and even the Turbocharger compressor cover can all develop boost leaks.This boost tester is exactly what you need if you work on diesel trucks regularly or just want to check the condition of your engine's charge system. Here's what you can get: Heavy Duty Regulator Extremely Accurate Testes Entire Charge system Precise control over test conditions Easy to use and read Premium partsbuilt to last for a lifetime High-quality seals Liquid gaugeprevents erratic readings Metal construction CNC Precision-Cut Adapter Perfect Fitment Clean look Intelligent design Madefrom high-quality materials Made and assembled in the USA Important Notice: This turbo uses a customized nozzle ring and/or shroud plate. Its been engineered to provide amazing response and performance. This turbo must only be operated with tuning that uses stock Minimum and Maximum Vane Position tables. Failure to do so can lead to excessive exhaust pressure and boost which may shorten the life of the turbo or engine and may void the turbo warranty. Damage caused as a result of non-stock vane position tuning modifications will be the responsibility of the owner, not Calibrated Power Solutions Inc.
