Enabling TuneUp only in dev mode

When I put config.gem ‘fiveruns_tuneup’ in my environment.rb TuneUp works perfectly. But, when I put this line in config/environments/development.rb, it does not activate TuneUp.
any ideas?

Hi Rémi,
TuneUp gem is designed to only go in the environment.rb file. However, it also only instruments the dev environment and does not instrument the production environment. So you should not see TuneUp in your production environment.
Let me know if you have any other questions.
Thanks,
Rachel

It seems that when I run my rspec(with autospec) or even manually, that TuneUp is enabled so I have to do this to enable it only for dev:
config.gem ‘fiveruns_tuneup’ unless ENV[‘RAILS_ENV’] != ‘development’
