Just wondering what is holding it back on takeoff,then the power kinda kicks in? I have an 06 2wd SE Ex-Cab with Big Tow package and Offroad package I guess? Locking rear fender box,Utili-Track,spray-in bediner,backup sensors,etc. Just bought it 2 weeks ago,and the power is ok,but not what I expected,something is limiting it............:huh:

Factory torque management. Just about every vehicle with throttle-by-wire these days has it in such a way that it limits power when mashing the gas off-idle. Newer Fords have the same deal in the Mustangs and trucks. They either reset the TM settings or deactivate the whole thing and replace it with a normal throttle cable setup and TPS. Not much you can do but get a custom tune for your truck via UpRev or someone else.

Wait til she has more than 5000 miles.
I think that's the point where the ECU determines that everything is okay and the firmware chip changes modes.

The ECU hold back the throttle from WOT till about 45 MPH, that's when you feel the power kick in. Like Blown330 stated, it's a kind of torque management. The Armada/QX does not have this feature. I guess with the added weight of the Armada/QX have at the rear end, they don't need torque management (that's why the Armada/QX is quicker too). Up Rev can re-flash the ECU to allow for WOT from the start.

I don't what others experiences are but when I bought my truck, it had awesome power on take off right off the factory show room. If you stomp it kinda hard, it would chirp or just spin at every stop light. My only issue was the power dip around 3500-5000rpm. After the 2* timming it fixed that. Everyone was saying that one should see more power after 5k miles but I didn't even notice a difference. My truck has been strong just the way it is from day one.

Well,it has 14,800 miles,so that 5,000 theory didn't work on mine. It does start picking up at about 45ish,below that,it will chirp on takeoff,but you can feel the mighty hand pulling it backwards. There is no tuner like Hypertech,etc. you can buy? I've read a little on here about the 2 degree advance,can you use that and the uprev tune at the same time?

it's the drive by wire crud limiting your throttle body, it won't open 100% till you hit 45 mph, only people that can get rid of this is uprev.. if your not willing to shell out 500 bucks for a custom tuned ecu, you will be stuck with this for all eternity..

Up Rev tune give you a custom timing curve so there's no need for the +2* when tuned. The +2* is great for those not tuned.

Unless you drive to their location in Austin, TX for a custom tune. Their end user product is in the final testing stage so you might want to wait for that.
