I do not have a Coyote based Mustang, so take this with a grain of salt.
Any tune is only as good as the customer service and after-sale support.
When making this decision, there is no such thing as too much information.
My experiences with mail order tunes is exactly why I appreciate my relationship with local shops!! Strongly consider fostering a relationship with a local entity before you go mail order.
But if you insist on using a mail order tune: VMP > Lund.
This is primarily due to BJ's level of customer support.
