Those with quad box?
Hi, I installed the Quad XZT+ box with the three settings that are controlled with a switch. My question is those that have this box can you feel the difference in power. I know the highest setting is only 65 more horse power but I really feel no difference. Truck runs fine and has no check engine light just doesn't seem to have the increased power it should with the box turned on. I have the map sensor plugs plugged in and have the two wires tapped. The only thing I can think of is the twist locks that are used to tap the two ecm wires may not be making contact. Not sure? Thanks, Frank

IMO you don't really notice a difference in hp unless your running a 100hp or more tune.
Remember this is an 8000 pound truck that already has 325hp (at the flywheel) 65hp isn't really that much of a difference. The biggest difference you'll notice is while towing due to all the extra torque a chip gives.
