We should still be able to tune your Mustang, even though you have the Jmod. We're just going to have to datalog to make sure the shift points are right since the transmission has been messed with.
Hit up the Bama team and they'll help you out! Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 9AM-5:30PM EST. You can hit them up directly at 888.226.9764 and they'll get you squared away!
