1 - Dodge 5.9L Cummins Boost Fooler

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. 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. 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 75ยฐF on a stock truck and up to 300ยฐF 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 Boost Fooler you will be able to run 35+ psi of boost depending on your fueling enhancements.

The 2004.5-2007 5.9L Cummins uses an electronic wastegate which is operated off of the MAP sensor. In this instance no modifications to your turbo will be necessary. Stock 04.5-07 trucks typically spike up to 32psi of boost pressure. With the Boost Fooler you will see up to 40psi of boost on a stock truck and up to 48psi of boost on heavily fueled trucks.

How does the core deposit work?

Pay a refundable core deposit so your part ships right away, or send your core first. Cores must be complete, undamaged and rebuildable, and returned within 60 days. Deposits are usually refunded within 10 business days of receipt. Return shipping on the core is paid by you.

When will my order ship?

Most orders ship within 48 business hours, free on orders over $250. Expedited shipping speeds up transit time, not production or sourcing time.

What does the warranty cover?

Depending on the part, products carry a 1-year or 2-year warranty against manufacturing and material defects. It excludes installation errors, fuel contamination, pre-existing engine conditions and misuse.

Can I return it?

Unused, non-special-order items can be returned within 30 days. Refunds carry a restocking fee of at least 15%; exchanges and store credit are fee-free.
