I know headpunter had mentioned previously that if you deactivate the AFM and do a tune the L99 pretty much equals a LS3. What I'm wondering is this - will GM and the aftermarket create performance parts like headers, heads, and cams specific to the L99 so that way you don't HAVE to deactivate the AFM? Also another question - does AFM hurt the performance aspect of the car?
