No tuning is required to install a boost elbow. However, always monitor boost with a gauge and avoid exceeding safe boost levels for your turbo/engine combo.
FAQ: Will this fit my 5.9L Cummins?It’s commonly used on 1994–2002 trucks with HX35/HX40-style turbos and on Industrial Injection Phatshaft turbos. If you’re running a different turbo, confirm your wastegate elbow/port compatibility.
FAQ: What boost level should I target?Targets vary by build. Many stock-frame HX35 setups run in the mid-20s PSI under load. Use a boost gauge and adjust gradually to stay within the safe range for your turbo and fueling.
FAQ: Any installation tips?Apply thread sealant, route a clean boost reference line, and verify there are no leaks. Recheck clamp/line tightness after a few heat cycles.
