You should be ok without having the uprev, but just keep an eye on things.
Didn't I read someone added some mods and was running lean somewhere, not sure what they were or how many mods.
Although saying that I swapped out my lower plenum and had no issues, and on the revup it makes nice gains so the changes were coped with and adjusted by the ecu with no issues.
Wonder if you can polish them up??
If not like you say clean it up and powdercoat blue.
