why do LS1's do this??
the ls1 has got most of its ***** up top that why they freak out with a big stall because it keep them in there "sweat spot" in the higher Rpms where there power is.
Oh, and when I go WOT and hold it, then let off the gas, the RPM's hang around redline for a few seconds before coming back down and makes a EEEEEEEEERRRR! sound. The RPM meter doesn't seem terribly accurate in the LS1 anyways IMO.
Headers, etc, also contribute to that feeling. Anything that increases stall or moves your powerband UP in RPM will cause that.

If the motor feels sluggish you might look into a tune, have your trims ect checked. If everything is running properly it shouldn't feel way down on power, even in the heat.
