If you stay with the JR or Delicious tune with standard pulley and add an oil cooler, your car will be faster than the STI (91 octane) and as reliable as stock. None of the problems reported here are factory configuration.

But to be fair, my tS is DEFINITELTY quicker than my Crosstrek Stage 0.

While this thread has put the fear of god into me with my upcoming JRSC C30 install, I’m acquiring all the supporting mods to try and run it as safe as possible and then cross my fingers and hope for the best!

Sorry some of you all have had some terrible experiences, but thanks for sharing so the community continues to learn and grow!
