"A few $$ more". PBD is double the price for SCT + tune, tiny bit more for Ngauge + tune: http://www.pbdyno.com/Naturally-Aspirated-and-Nitrous-Tuning_c_388.html300 bucks will get your car tuned. Or maybe a few $$ more.
I'd go that route.
Lund is nearly double for Ngauge + tune at $579: https://www.lundracing.com/ngauge-2015-2017-mustang
