Once you are looking to go beyond the performance of our basic Stage 1 Package, you will reach the limitations of your factory turbocharger. At this point a turbocharger upgrade will be required, along with appropriate upgrades to the exhaust, air intake system and intercooler. With these upgraded items we are able to squeeze more performance than a stock setup will ever provide.

Looking for maximum GRUNT without compromising factory reliability? Our Stage Three Package is for you! This package will give you the ultimate in diesel performance, with massive gains available in power and torque.
The main difference between our Stage Two and our Stage Three Package is the addition of high flow fuel injectors. In a diesel engine, more fuel = more power, provided you have the air to burn it! We also only have a small window of crankshaft rotation available to inject the fuel. High flow injectors allow us to increase the amount of fuel delivered to the engine during this window, resulting in huge gains in power and torque.
*power and torque numbers will differ between vehicle models and final diesel performance packages and tunes. Our increase numbers should be used as a guide only. Different vehicle makes will have variations in the packages we offer, not all packages come with intake cleans.
