FYI - I tried a boost fooler in two different configurations with what I consider to be poor results.

First was stock, no other mods. The boost fooler created a serious lag on the low end power. I assume this was because the boost fooler was telling the ECU "nope, no boost, okay some boost, a little boost now, okay a little more", and the ECU would then respond by saying "no boost? okay, just a little fuel then, now you got some boost? I'll give a little more fuel," etc.

Basically, I believe this moves the whole power curve to the right, and peak power or TQ won't be made until later. Even so, no more power than stock can be made, and the benefit of more air in the cylinder would serve only to cool EGTs. In the end, I don't think the positive benefits of having more air stuffed into the cylinders makes a difference when the fueling lags way behind stock levels. In other words, i think a boost fooler on a stock truck will reduce power. It also creates the risk of an overboost situation.

The second configuration I tried was with a fueling-only box, the Diablo Predator Puck. How the Puck works isn't widely known, but from the effects it has on my overhead display and the method of installation, I assume it's a fueling fooler. It basically tells the ECU "you don't have enough fuel for this throttle position", so the ECU dumps more fuel in than it normally would. (I think the amount of fooling varies with throttle position, and overall the Puck is a good product... it does what it says it will do). I came to this conclusion when I found the Puck at 90HP setting caused my overhead to read around 24 MPG at highway cruising speed on flats. Obviously my truck is not getting 24 MPG; what it indicates is that the ECU believes it is fueling at a lower level than it really is, so the calculation reads high.

It would make sense that the boost fooler would be beneficial with this box, because more fuel would do better with more air stuffed into the cylinder. However, what really happened was the boost fooler created the same effect as it did when used with the stock setup. I had a huge lag off the line.

I thought about this for a while and figured that the boost fooler was once again doing its job, and the ECU was fueling appropriately - in other words, less fuel for the reported lower level of boost. Even though the Puck was doing some fuel fooling and was helping to fuel more than stock, the boost fooler actually canceled out the effect a little and worsened performance off the line.

There's probably good cause to do some boost fooling at higher RPMs, loads and speeds (to keep EGT's down), but I don't drive like that and I never tow with any performance mods activated.

I removed the boost fooler, and the truck responds very well to the Puck. It's fun to zip around a little and have the power on tap without lag.

All of this is JMHO. I'm no expert.

 

I've read either on the Diablo or Quad site NOT to use the BF with a chip. Craig

 

The Diablo puck does pressure....thats no secret.

Which one was plugged in directly to the MAP? switch them and try again.

It is ok to use a boost fooler with a Diablo Puck since it does not do boost fooling.

was this a Quad boost fooler?

 

The Puck was plugged into the sensor plug on the block, then BF after that, as was recommended.

The lag was just too much. I've seen Qzilla say that the BF doesn't do anything to the MAP signal until the truck is near bax boost levels, but my truck just doesn't respond that way, and I know others have had the same problem.

 

Mine does not have that issue. At least not that I have noticed. I have the fooler plugged into the block and then the Puck.
Be aware that the Puck raises the rail pressure over 27000psi even on the 50hp setting. I don't even really have to be pushing the truck too hard in order to see this. Mine is turned off for that reason...

 

You're running the Predator/Puck stack, which has different fuel maps. The Puck can only modify the stock fuel maps...

Now that you've brought up the point of where to put the BF, I don't even know any more... I've seen experts tell it both ways.

 

Interesting. I don't recall anyone recommending to put the Quad BF anywhere except into the connector on the block and any boxes should plug into the back of the BF. That's how I have mine and don't notice unusual lag. I'm no expert though, and I've never tried them swapped around.
Maybe you can swap yours around and let us know what you find.

I have run just the Puck without the Predator on the truck too...

 

i have the puck and quad fooler on my rig. before the fooler I would trip the overboost code in the computer, which some people have said cuts fuel back to the engine for safety reasons. i havent really noticed and really bad lag. i dont get much smoke though. do you guys get much smoke on the 90hp setting?

 

I really like my Quad Boost fooler no lag or unresponsiveness .

 

I was thinking about this a little more. If the BF goes to the sensor plug first, then the Puck or any other fueling box that follows after would be fooled also. I figure you'd want the fueling box to get the most accurate information possible from the MAP sensor so it would fuel in accordance with the actual boost levels.

 

how much smoke is everyone getting from their puck on the high setting? i think i have my fooler plugged in after the box and I really dont get much smoke at all. is that normal? or should i swap them around?

 

I get some smoke but not a whole lot....
