Ok Put The Boost Fooler On The Truck And It Sometimes Will Give 25lbs And Other Times 40lbs. If I Roll Into It Slow It Brings Up The Big Boost But Nail It And Low Boost. Any Ideas??? Im Ordering A Sps62/14 This Week And Dont Know How To Control Boost With That Turbo. Any Help Would Be Great.

 

Assuming this is the Quadzilla Boost Fooler, check the MAP sensor connection and use dialectric grease. If you still have problems, call Roark at Quadzilla on Monday. 817-306-2444

sps62/14.....I have one....also called a SPS6280...same thing.

Industrial Injection sells a fooler for the turbo end of the sensor to keep the ECM happy....this keeps the ECM happy but not the MAP sensor. You will still need a boost fooling box (or a Quadzilla Boost Fooler) to prevent overboost codes while using your Crazy Larry programmer. There is a manual wastegate on the turbo but i don't see any need in messing with it yet in my situation.

For me, the Scary Larry adds a bunch of fuel...and the Quadzilla XZT adds some pressure and does boost fooling for me. it works together beautifully
