I assume you are referring to the "new #'s" being those of the LLY engine vs. the LB7 engine? The LLY has modified heads, remounted injectors, a variable-vane turbocharger and a cooled EGR system - just to name a few. That's a lot more than "just a chip!" The significant differences in the engines mean that much of the new technology is not backwardly compatible to our LB7 engines, either. Now, there ARE a lot of aftermarket chips and tuner options available to us for the LB7 that can give you that much increase in HP and torque or more. I recommend you do some reading in the Power & Performance section for that!
