for the jeep srt8!! do we have it? can we get it? will this help with adding power from low to mid to high end?????????????????????

No the Jeep doesn't have VVT and it's not something thank can be added or modded (unless you have a lot of money).
VVT actually slides or rotates the cam shaft(s) to change valve timing according to rpm/speed.

The new 5.7 & 6.4 have it.

go it! thanks guys. just fig i'd ask.
