D40 Navara STX550 V6 ECU Remapping & Tuning

When Nissan released the D40 Navara they added space, refinement and creature comforts that the market had come to expect, including a much more modern and muscular appearance. Nissan did give the D40 more power over the D22, however who wouldn't like even more to haul their tools around during the week and toys around on the weekend?

Here at Indepenent Motorsports we can can reflash a vast range of Diesel and European vehicles, including your D40! We read the factory ECU file and make changes to the relevant tables such as boost, injection timing, injection pulsewidth and torque limits. This is a fancy way of saying we are able to safely calibrate a tune that will not only make maximum power and torque but with all of the advantages of factory safety limits. We closely monitor AFR’s and EGT’s whilst performing our custom tunes, ensuring that we get it right every time.

So if you're looking to get your D40 Navara running as efficiently as possible without compromising on the factory driveability, give us a call and book in your car today!
