Product Rocks

First off you didn't go from 52 psi I call BS. Took my 04.5 cummins from 38 ish psi to 48 psi with bullydog, prob may not be the Boost fooler guys it may be simple operator error and the junk programmers your using. try BD never had issues (other than a good clutch). I also noticed a drop in EGTs while pulling hard. Never had any issues with fault codes etc due to this product, and i don't expect that anything will change there. Even without the programmer i noticed a modest 3 psi gain in boost, which you can tell. THIS THING ROCKS

plugs did not match up exact. I installed it and it pushed the pin on the stock wiring harness out of the plastic plug. I had to re connect another plug to my stock harness.(A Pain) The boost fooler worked as advertised though. about 44#s of boost with smarty and about 1.25 miles per gallon better on fuel economy.

the boost fooler is junk, i have a late 04 cummins and it is junk. it makes 40 with it and 52 with out it. that is running diablo sport predator on economy setting(100 horse)
horrible product BUY THE BD BOOST FOOLER--But XDP is awesome

I had nothing but problems since I installed this. a few hundred miles down the road it caused a turbo underboost code which puts the truck into limp mode and you lose almost all power. this happened to me on the highway while towing 8k pounds multiple times making it hard not to get hit. Took it out and not a problem since. and I told quadzilla and they did NOTHING to help. Buy the BD boost fooler! its a great product and a company that stands behind their work. This one is JUNK. But on a better note I have had nothing but great experiences with XDP so buy from them!!
08 6.7L with smarty tnt and mp8 no diifference

with the smarty and mp8 its boost abot 35psi i put on the boost fooler and the was no change in psi the only change is now my gauge needle bounces between 34 and 36 really fast at peak boost
Works perfect on my 04.5 dodge

Dont Buy a Quadzilla they wont stand behind it

Mine worked well for about 6 months then started causing codes. Took it off and no codes for 2 months Called Quad they said teh fooler is the problem "we have seen that before" but you are out of warrantee so too bad. I say buy a BD they stand behind the product they make! thats what I will do next time
dont waste your money like i did

dosent work on o4.5 dodge with bully dog programer takes longer to build boost than before boost fooler installed still only gets 30psi
More boost
brandon (portales NM) 7/17/2009 4:06 PM
all im running is a diablo sport on extreme gauges intake and i was gettin about 33-34 psi not towing and now with the boost fooler im gettin 44-45 psi huge difference easy install and dropped about 50degrees on the pyro worth the money on the 05 cummins
Waste of money on 6.7

Doesn't work on 6.7 engine, throws EGR code every time with exhaust brake engaged. Needs more testing by company.
greg (canada) 5/7/2009 6:09 PM
if you own a 6.7 dodge then don't waste your money. It does nothing. A total waste of money
Good bang for the buck!!!

awesome product, takes less than 2 minutes for the install. It did add some boost, I would recommend getting the BD Waste-gate, the two go awesome together for optimum boost gains. Plus the waste-gate is inexpensive, and adjustable.
Its alright

If your lookin for more smoke it doesnt help that. But it sure does make ur truck alot louder!
