I bought my 2011 mustang gt in late 2010. So far there have only been 2 mods, muffler deletes and drag radials. I don't track the car at all and on my daily drive to work I consider it therapy. I pass in 6th most times I don't even have to down shift. I'm coming up on 60k miles and I'm wondering about a custom dyno tune purely for the sake of health. Obviously vehicles deteriorate over time and compensation for said deterioration might be had in an updated tune, so my question is (assuming I'm keeping this thing until it has 150k miles because its perfect) will a custom dyno tune actually help vs hinder in the sake of keeping it alive?
