For 2007.5-2015 Dodge 6.7L Cummins

The Quadzilla DBSTF67L Boost Fooler is a must have on your 2007.5-2015 Dodge 6.7L Cummins. If you tow heavy loads, are using a downloader or programmer or running modified injectors, the Quadzilla Boost Fooler will help you get the most of out of your truck.  While programmers can definitely improve performance, there are still things that they cannot do to allow you to gain optimal power and efficiency out of your engine. The Boost Fooler will allow you to increase turbo boost to compensate for the added fueling modifications you have made. Enabling your turbo to produce more boost will increase overall horsepower and torque and lower your exhaust gas temperatures.
The Boost Fooler is also a great enhancement for a stock truck that hauls heavy loads and needs exhaust temperature reduction. Even on a stock truck you can easily gain 5-8psi of boost pressure to help cool your EGTs. You will also see a slight improvement in peak horsepower. The Quadzilla Boost Fooler uses a specialized high impedance circuit to allow you to make more turbo boost without setting any ECU error codes. The Boost Fooler is 100% weatherproof and designed for simple under-the-hood installation.
You will be able to make as much turbo boost as possible with your fueling modifications. It is important to notice that the stock turbos do have some limitations. If you desire extreme levels of turbo boost, you may need a larger, aftermarket turbocharger. Horsepower gains will vary from 10hp on a stock truck up to 50hp on heavily modified trucks. EGT reductions will vary from 75°F on a stock truck and up to 300°F on heavily modified trucks.
On 2007.5-2015 6.7L Cummins, the turbo uses electronically controlled vanes inside to adjust boost levels and allow for quicker spool up and the ability to precisely control EGT's. With the Boost Fooler installed you will see drops of 125 degrees on a stock truck (considerably more on modified trucks), up to 10psi peak boost gain and 6-8 psi sustained boost gain.
