With a possible ECU remap for you, check the link below out, can put a word in for you. What exhaust will U be using?

Something to think about - Harley is the contact (email) to follow up. Postal remap $750 + postage (say $790) and 1-2 wk turn around. You remove ecu send to them direct and they post back. Good tune, you set boost/spool and all good (Max boost 20-22psi / AFR around 22:1). They turn off EGR as well.
With remap, IMO need to improve induction to allow turbo to breath easy.
