I have had the Edge Juice with attitude stacked with the Tripple Dog w/ outlook monitor, The dyno shows 380 hp stacked 375.1 with only the edge and 374 with the Tripple Dog. I was told that stacking them would make considerable differences, that is untrue. If anyone gets a chance to go to the Houston DHRA event next year definatley go. Awesome trucks great information and lots of horse power! If you are not in the 12s your not as fast as they are! I thought my truck was pretty quick (there that thought word came in) WOW these trucks were crazy! everything you could ever dream up they had! It was great. By the way if anyone is looking for an Edge Juice w/ attitude let me know I have one 4 sale!
