How do you want to tune and how much money do you want to spend?

Custom tune from reputable shop/tuner on their dyno for max gainz? Call them up and talk to them to see what they recommend. Get 2nd opinions. Talk to existing customers.


Cheap solution, canned/off-the-shelf tune, find a reputable header (look for build quality) and choose based what sound you want to live with on a daily basis. Don't overthink it, there's more time to be found in autox in driver and car setup than an extra 5-10 hp.


Somewhere in-between; make a judgement call, hell ping the STX build thread to see what other people are willing to share. There are quick STX cars still on stock headers and people who have dropped the big bucks for the ACE+custom tuning.
