I won't think any retuning would be needed. Even if you have slightly higher fuel pressure the ECM will read this and shorten the injector pulse to compensate. Might take a few miles of driving before the CEL reflexs the change. The only time you really have issues with high fuel pressure is trying to get a good idle as the ECM can have difficulty managing large (50+ LB ) injectors and high fuel pressures as it only uses 1 cell for cold idle operation.
