Decided to Run a few tests on some modifications you can do to get more performance out of your vehicle without compromising reliability. Percy the Prado has done 215,000km now so Tuning and chipping isn't really a option as we want the car to take us around Aus towing. Decided to get a EVC throttle controller and manta 3inch exhaust system. The Throttle controller takes the lag out of the throttle which turbo diesel engines are known for and the exhausts lets the car breathe better with more flow and less back pressure. The bigger exhaust also allows allows the turbo to spool earlier and also reduces EGT (exhaust gas temp) which can be an issue towing.

thanks for watching guys
