There are (generally) two classes of tuners. Those who make the cars everybody and their dog wants - Enzo, fully tuned ZR1, highly tuned GT-R - and as a result they get a lot of attention and praise simply because the tunes exist for people to use. Then there are those who do their own thing with little to no interest in the mainstream models and as a result nobody cares much.
The funny thing is that quite often the truly better tunes can be found in the second group. And one fact stands - something can be the most popular out there by a large margin but it still doesn't mean it's actually good.
