Frequently Asked Questions
Do I need a custom engine tune for a compound setup?
Yes, you absolutely need a custom calibration to make this work. A stock computer cannot interpret the massive jump in airflow and will likely put the truck into limp mode immediately.
Will this setup hurt my fuel economy?
It depends entirely on your right foot. While the increased efficiency can slightly improve mileage during highway cruising, the temptation to use all that extra power usually leads to worse fuel economy.
Can I still tow heavy trailers with compounds?
Compounds are actually better for towing than most single turbo upgrades. They provide instant torque down low and keep your engine cool during long, steep climbs.
What is the average cost for a complete kit?
You should plan to spend between $5,000 and $8,000 for a high-quality compound kit. This price includes the turbos, piping, manifolds, and the essential hardware needed for a bolt-on job.
How often do I need to service the turbos?
Maintain your engine oil religiously, as turbos thrive on clean lubrication. If you change your oil every 5,000 miles and allow the engine to idle down before shutting it off, these units will last for years.
