Not a M0derator
No. but that could be caused by all the monkeying you did with the idle screw and throttle cable. If it didn't idle high before, it shouldn't idle high now. And your tuner shouldn't charge you for another full tune. this is just idle. Usually tuners would charge per hour for that. No dyno required. Could even do it remotely if you had a wideband.
