Yes you need a tune after installing Catback and after market intake system especially when you decide to install HFC or test pipes. The car will run lean and none of us want to deal with that matter of fact, tune will help your car get the most out of your mods and make you smile and say it worth every penny.
As for which tuning software you'll get, I suggest you ECUTEK its far more advanced than basic software that Uprev have for us.
Contact
Visconti for more information about tuning how to go from there.
I strongly suggest you to do all of the tuning thing after the HFC (If you're planning to)
