I've asked the same question, and given the minimal gains from this tune, its honestly not worth impacting the ESP.Has anyone with an extended warranty (bought through Ford) been told the implications of this tune? I can’t get a straight answer on whether or not this warranty piggybacks off of that or stands on its own.
If the warranty with tune is on its own it would take my extended coverage from 90,000 more miles as of right now vs down to 36,000 or whatever the tune comes with. Not great.
Just gonna shift the money over to either modding the GT350 or going after one of those sweet new quad motor Rivians R1S lol
