I got an email from DiabloSport today and noticed that the tunes for the 15-16 ST put out a lot more power than the tunes for the 13-14 ST. Why is that? Did the 15-16 ST get a larger turbo? I'm curious to know.

2013-2014 Focus ST
93 Octane Performance Tune | +30 HP / +49 TQ
91 Octane Performance Tune | +10 HP / +45 TQ

2015-2016 Focus ST
93 Octane Performance Tune | +35 HP / +85 TQ
91 Octane Performance Tune | +30 HP / +80 TQ

Ridiculous. If those up/tq #'s are essentially the same tune from 13/14 to 15/16 it's BS. They have the same turbo. Only difference is the 15/16 have some brake upgrades, and interior/exterior styling differences.

Just called DiabloSport and the salesman I spoke with asked a tech who said the tuning parameters allow them to go a little further in the 15-16 ST. Not sure if I believe them. We'll have to wait and see dyno confirmations on this one.

Dont believe them. There are plenty of 15/16 owners and tuners on this forum that I would trust more so than Diablo.
