That's interesting Innovative would say to use an older strategy. The overboost issues were resolved in FSOQ and later strategies.
Taken from SCT website
Issues Resolved in this Tune Revision:
- Adds support for the new FS0Q00 strategy released by Ford
Notes: * 6.4L Over boost Codes: This latest tune revision attempts to resolve the over boost codes being experienced by many of SCT customers. These errors began when Ford released the P30 strategy. These errors were not caused by SCT or our devices, but were caused by the strategy itself. Instead of back dating PCM's to older strategies and putting our customers warranty at risk, we have released a this tune revision to help stop Over Boost error codes.
NOTE: You MUST be running the newest version of the P30 strategy from Ford or you MAY still experience Over Boost codes. These codes cannot be resolved if the vehicle is using the first release of the P30 strategy. SCT recommends having your Ford 6.4L updated to the newest P30 strategy at your Ford dealer. Once the latest P30 strategy is installed in your vehicle by Ford, you can then take advantage of this latest tune revision.
NOTE: This Tune Revision is only designed for SCT Part Number: 9623 or 9625. Installing this tune revision on a non-9623 or non-9625 device will result in an error and may require you to contact SCT Technical Support to restore it to the proper tune revision.
Unsure if your truck has the latest P30 strategy? Go to DTC Data Functions on your SCT device, select Read Strategy and look at the Engine Part Number. If it matches the below part numbers, your truck has the latest P30 strategy.

Everytime I talk to someone with a 6.4 and they have overboost issues, they're usually running old strategies.
