π₯ AUDI Q7 3.0 TDI β PERFORMANCE & RELIABILITY RESTORED! π₯
This Audi Q7 3.0 TDI came into Apex Automotive looking for more than just extra powerβit needed a solution to years of carbon and soot build-up.
After a full inspection, we found heavy soot deposits throughout the intake system, a common issue caused by the EGR (Exhaust Gas Recirculation) system. Over time, the EGR continuously recirculates exhaust gases back into the intake, allowing soot and carbon to accumulate, restricting airflow and reducing engine efficiency.
π The amount of soot that had built up was incredible!
π§ We carried out the following upgrades:
β
Custom ECU Performance Tune
β
EGR Delete
β
DPF Delete
β
Catalytic Converter Delete (CAT Delete)
The Benefits:
π Increased Power & Torque
β‘ Sharper Throttle Response
π¨ Improved Turbo Performance
β½ Better Fuel Efficiency (when driven normally)
π₯ Reduced Exhaust Backpressure
π οΈ Eliminates future EGR-related soot build-up
π¬οΈ Improved engine breathing and reliability
With the EGR system removed and professionally calibrated, the engine can now breathe freely without continuously filling the intake with soot and carbon, helping to keep the intake system much cleaner over time while delivering a far more responsive driving experience.
At Apex Automotive, we don't use generic tuning files. Every vehicle is professionally custom tuned to suit its exact setup, ensuring maximum performance, reliability, and drivability.
