Taking out the old LS, swapping pan, covers, intake and accessories from the old engine to the new and installing long tubes while its all out is one long day of work. My dyno tune cost $650, but that included any touch ups I need if I find any little drivability issues down the road. (Only had to go back because check engine light kept coming on for "traction control inop) he had forgotten to turn it off in the tune.
