Anyone notice downsides to ZFG tune? I have a stock 2020 ST on lease. I really like the ST and thinking I will buy the car off lease, if I don't have any major issues. My lease is for 12K miles a year, and I'm driving in excess of 15k right now, so, with over mileage charge it probably will make sense to buy it. I've read plenty of positive reviews, but are there any downsides? I like what I am hearing about shifts points, etc. The truck is "quick" now, but of course I would like it to be faster. Does a tune make sense if I am not considering any other mods? Any impacts to vehicle reliability or longevity?
Thanks
