The learn down feature that is programmed into your ECU is what GM did to keep the power the exact same regardless of the modifications you have done to the car. It will automatically pull timing and adjust fuel levels and air levels to keep the SAME power that it had from the factory.
Seeing as tho your car is an LS, I honestly don't think you have that in your ECU as they really only put that on the SS models because they are boosted. That is a safety feature that GM put in there so people wouldn't blow up their engines with modifications to the engine with bolt ons, but it also assured that even with full bolt ons ect, they may SEEM faster but they actually aren't until they are re-tuned (thus voiding your warranty) unless you get the GMS1/2 kits. That is the learn down and reason for it. But again, I honestly don't think the 2.2/2.4's had that in the ECU. At least with all the ones I've tuned it wasn't in there.
