i did the exact same thing. i didnt need a tune! basiaclly i only had the problem of the security light. once i did the relearn, started right up. everything is v6 except the motor, acc, harness, fuel line,... i re used the 02's and maf i believe.
keep vats, its not an issue, plus the motor isnt in something its not supposed to be in. like ours..
