Pick any of the many 90HP tunes with low boost fueling turned on and cutting 1.9s 60's on stock tires for a 7,200lbs truck shows the low end is there.

It's rediculous the difference a simple programmer can make. 
Stock, the LLY does feel pretty doggy until just a little over 2000rpm.
Not even gonna pretend I've never done it myself.
