you can go stand alone but of course you will need someone with knowledge to tune it. piggy backs are ok to a certain point. If I were in your shoes, oh wait I in a sense sort of am get an Enthalpy tune, if you havent heard of Enthalpy AKA Scott formerly from secret services you should not own an SR, Visit freshalloy.com and you’ll see he knows his SR tuning. The tune is about 500 bucks which is on par with JWT but the tune is by far superior, thats the route i will be going very soon
