That pretty much sums up the same conclusion I came to when messing around with the "optic bump." It even messed up my cruise control: it could no longer hold steady RPM when going down hills. Took me a long time to get it back to normal operating parameters. Then the IP failed and I replaced the whole thing anyway.
