Designed for Towing & Daily Driving
This turbo is ideal for drivers who tow heavy and want faster spool. At the same time, it avoids the lag often found in Stage 1.5, PMax, or Stage 2 turbos. As a result, it delivers strong low-end torque and smooth power across the RPM range.
Tuning Recommendation
For best results, we recommend using 50-state legal Edge or SCT tuning. Proper tuning helps maximize performance while maintaining reliability.

Exhaust Brake Compatibility
These turbos can retain OEM exhaust brake functionality when the vehicle calibration allows it. However, some aftermarket exhaust brakes may restrict exhaust flow. Because flapper-style systems create excessive backpressure, we do not recommend using them with this turbo.
