The overboost codes are going to stay. The van tuning definitions aren't as complete as the trucks simply due to the popularity (or unpopularity rather) of the E-series. If the code bothers you that much, you will have to install a "boost fooler" of some sort.
Anyway, don't worry about the P0601. It's no problem.
As for the "throttle" response and downshifting, the tuning on the chip doesn't change over time. The ONLY way the tuning can change is if it's done with the appropriate programmer and software. Something changed with the van.
