I gotta agree with Rob on this one. <br><br>I'm running DD3's and a TST PM-2 with a EZ stacked on it and they work great with each other. My EGT's are higher running the EZ by it's self but with the PM on they drop almost 100*. ??? Not sure why I get a drop in EGT's with more fuel but that's how it worked. :<br><br>DB

 

Just curious, since the 60' times and 1/4 mile times were very close in your test and you attribute the difference to the stacking and un-stacking on the boxes, were your reaction times exact?<br>Steve

 

Reaction times do not effect the 1/4 mile times.

Not trying to add controversy to the pot......but, (and please don't be offended)

The first run was done stacked.
The second run was done un-stacked.

Was there a third run stacked again (to backup the stacked run) to verify results? This would eliminate questions concerning &quot;fluke runs&quot; (similar to a &quot;backup&quot; run when setting a new E/T).

Also, a fourth run un-stacked would give positive proof of improvements. Two stacked and two un-stacked.

 

Pardon my ignorance, but what is a fueling box and what is meant by stacking them?

Just to throw in some more numbers, I dynoed earlier in the year when I had my DD2's with and without my EZ. With just the TSTPM3 Comp I dynoed 378hp.... with the EZ stacked I dynoed 413hp. 35 exta horses for any one who cares. <br><br>Horace

 

A couple of years ago, when Edge was first introducing the Comp, we had a mini dyno afternoon at Edge. Heberam, drawson, and myself were there getting lots of good dyno time. <br><br>I had been running an old 3 level Power Egde &quot;beta&quot; box stacked with an EZ. When I tried the new Comp, I lost 10 hp over the stacked combo. The Edge folks, Taylor and Brett, weren't surprised.<br><br>Stacking worked for me until the old Power Edge gave up the ghost, a couple of months ago. It was too old, and one of a kind, so Edge couldn't fix it. Forced me into a new Comp.

 

Kat:<br><br>Thanks for the comments! <br><br>----------<br>DanStewart:<br><br>Yes, my son made more runs that night and each<br>time the runs were faster with BOTH boxes<br>connected.<br><br>----------<br>Mark Thomas:<br><br>DTR member Doug made a good explanation of how<br>&quot;stacking&quot; works, but let me try to answer your question<br>on what a fueling box is. I know the membership will also<br>add to what I post.<br><br>Fueling boxes are basically small computer modules that<br>that add power to the 24 valve engines by adding fuel<br>and increasing boost. They hook up in somewhat different<br>ways, for example an Edge EZ plugs into the engines<br>MAP sensor and into the data port. Basically, (and I mean<br>this is VERY basic ), the fueling box is telling the<br>engine that &quot;fueling is normal&quot; but in reality it is not.<br>In the case of the TST PM 3, it is adding mainly fuel<br>and boost, but does not increase the timing by alot.<br>So,.....we add an Edge EZ or a DD TTPM which adds<br>more timing. This helps low end response as it did on<br>my son's truck and also on mine and others.<br><br>This was kind of a &quot;simple&quot; explanation, but I hope<br>it helped you some! As I said, I am sure the other<br>members can add to this.<br><br>-------<br>John_P
