Test drove an 06 today.
Truck looks absolutely stunning, a banker here pulled his 5th wheel with it 65% of the time and the rest was general driving.
It is a 4x4 Lariat, 112k. Truck is as tight as a 40,000 mile ride and looks according other than a few minor door dings.
When we test drove it, the thing ran like a top but felt under powered (after just 3 or 4 minutes of running). I didn't hammer it but about 3/4 throttle I thought WTF this is a great looking truck but runs like a dog.
So I babied it for about 10 miles, turned around and eased into it at full throttle it and it started squealing the rear tires.
My question is,, does the computer "de-tune" the engine until it is warm or is it something else?
The truck ran night and day different.
We had an 04 and it ran real good all the time.
Thanks in advance,
