928 modifications were done in 2016. so far after 40k miles and countless dyno run and log pull it is still holding good. although the supercharger does leak small amount of oil. It's about time I change the oil seal in the SC.
It all depends on the tuner and his skills in getting the most out of the mods. If the tuner is good, he knows how far he can push the mods without a disaster.
