Does anyone know if there is any kind of mod we can do to the engine to get more horsepower?

Haven't seen any. One of the other strings a while back noted that you used to be able to replace a chip controller as an aftermarket. However, with the XLR, you must recode the computer and apparantly GM is not allowing anyone to know how to do this (you'd have to hack the code). This would undoubtedly affect the warranty.

Anyone else have thoughts?
