I actually know nothing about LS Engines or what generations are what. All I know is that they can be rebuilt way better than OEM, especially without afm.
You guys on here know your ****.... all I know is many reasons why I wont buy a new vehicle with all that crap.
being a member on GMTC Iv read many afm horror stories and gm treating those people like crap. I researched into it far enough to think that the VLOMF is probably responsible for most failures. every damn filter in a vehicle has a scheduled maintenance except this one.
I think the next huge problem in GM that's just starting to pop up is Soy based wire insulation. it tastes great to rodents.
