Anyone regret having ECU Ivanized?

[bsilver1968]

I've been reading several threads about the Ivan ECU flash. I have a 2016 Vaquero with 300 miles that is stock except for Mustang seat and a Clearview windshield on the way. I am on the fence about doing the Ivan flash.

Some people have talked about having a high idle at startup, engine not warming up when the weather is cold, possible extra carbon on the pipes from running rich, hard to restart like the engine is flooded, etc.

To the guys who have had this done, is there anything that has happened that made you regret your decision? When the temperature is cold does the engine eventually warm up and the idle return to normal or does it idle high the whole time?

Thanks for your insight. I think this is my first post here so if I did something wrong, forgive me.
