Description

When larger Turbo Chargers are added to these trucks the usable RPM range is shifted up. Engine speeds where a stock turbocharger would be happy, may be laggy, smokey, or hot on the pyrometer after the addition of a larger turbo. Tuning the transmission on these trucks is the best tool available for making sure the engine is operating within its preferred rev range.
