And there has been other conversion like a full hemi swap and a LS swap, full kit new ls computer and harness and all the goodies to have the ls run in a XFire will cost the same as just a tune to make a 5.0 mb engine run, but also have to change out gauge cluster, wiring, ignition etc.
As I said depends on budget and what you want to do with it.
