If you are towing heavy loads, using a downloader/programmer, or running modified injectors then the Quadzilla Boost Fooler is a MUST HAVE PRODUCT!

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 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 (depending on fueling mods). 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 1998.5-2004 5.9L Cummins you will need to physically modify your wastegate to gain more turbo boost. Doing this without the Boost Fooler will result in check engine lights and codes set into the computer. Stock 98-04 trucks should generate 18-23psi of boost pressure stock (depending on year model). With the Quadzilla Boost Fooler you will be able to run 35+ psi of boost depending on your fueling enhancements. For these year trucks, we suggest using an Edge boost elbow.


Reviews

  • I have a 2007 5.9 3500 and i’m getting a p0236(boost pressure sensor) code i have replaced sensor 3 times still getting code, the truck is 2nd gen swapped with 60% over injectors, fass fuel system, and a 5 position switch, just wondering if this will make the code go away?

    This item is for an over boost code, but the 236 is a sensor or wiring issue. no other codes?

  • Do I need a boost elbow and boost fooler? Why both ? What if I have a adjustable waste gate?

    Tim Tarnowski | 8/26/2023

    No, Fooler will still help,with the adjustable Wastegate.

  • What do they mean physically modify the waste gate what do u gotta do to it

    Wes Perrin | 3/7/2020

    Manually adjust the wastegate. This will allow truck to build more boost. But it will throw a over boost code, without the boost fooler.
