how do i make this concurrent?

Client.scala

// we want to be asynchronous here because we are doing several API calls
  def crawlProjectRepos(project: String):Future[List[RepositoryCommitList]] = {
    Logger.info("crawling " + project + " by API")
    val repos = reposFor(project)
    Logger.debug("REPOS " + repos)
    for (repo <- repos ) {
      Logger.info("REPO STATUS FOR " + repo + " : " + Await.result(callApi(buildCommitUrl(project, repo)), Duration.Inf))
    }

    val goodRepos = for {
      (repo, res)  <- repos.map { repo => (repo, Await.result(callApi(buildCommitUrl(project, repo)), Duration.Inf)) };
      if res.status == 200
    } yield (repo, res)
    Logger.info("SHOULD ONLY CONTAIN 200 STATUS " + goodRepos)
    val repoCommits = goodRepos.map { gr => //repos.map { repo =>callApi(buildCommitUrl(project, repo)).withFilter(_.status == 200).map { c =>
       Logger.info("RETRIEVING FOR " + gr._1 + ":" +gr._2)
       scala.concurrent.Future {RepositoryCommitList(gr._1, (gr._2.json \ "values").as[List[JsValue]].map { commit =>
          Commit(0,
            (commit \ "id").as[String],
            (commit \ "message").as[String],
            (commit \ "author" \ "name").as[String],
            (commit \ "author" \ "emailAddress").as[String],
            (commit \ "authorTimestamp").as[Option[DateTime]](Reads.optionWithNull(jodaDateReads("yyyy-MM-dd'T'HH:mm:ss'Z"))),
            None,
            Option(new DateTime),
            Option(new DateTime)
          )
        })
       }
      //}
    }
