Get out one of your ebay 7749's and build a bench flash harness for it, and fire it up on the bench. Make sure it responds appropriately to a datalog first-then the ostrich, then datalog the ostrich, then into the car AFTER you check your wiring harness.
As far as boost control, you've already found your problem if you can't even get it to hold boost with a manual controller. If a manual controller won't hold steady boost, the ECM will not have a chance! Get that wastegate under control first, then try the boost controller again.
