I would assume you have a separate issue as none of ours with this routing has effected anything. And I have never had the code 25 in these 2 seasons so far. You can try to tee in elsewhere. Or possibly swap gauges sensors with someone and see if the issue isn't with your actual boost gauge/sensor aside from the code 25 you now have. Which points towards a bad connection wire or boost pressure sensor on the sled itself.
