Who has hondata with plus 6psi on their si and how long have you been running it? I'm on the wall of buying the new 2018 si. Just don't know how much room there is for improvement in performance with keeping it reliable
We've been running the FlashPro on our shop / race Si for almost a year. Recently added E85 to the mix. Zero issues and huge power gains over stock. This is not to say the increased power doesn't put more strain on the motor...it's just that Honda built this thing so well I believe it's going to last a very long time even with our aggressive tune.

If you want to play it safe, just load the Hondata +6 PSI basemap and enjoy a substantial power bump with probably no measurable decrease in long term reliability.
