I previously had a highly modified sti with a 20g and supporting mods, I ran a turbosmart e-boost ebc with it. My question is can I still use that ebc in my evo IX or will it not work with my evo? The other part of my question is if I'm able to use the ebc can I run 3 gals of 101 octane mixed with our ever famous California pump 91? Is this safe on a otherwise stock car? I still want to keep it stock for a little while longer but I want a little extra power and responce. The purpose of doing this is just to hold 19-20 psi to redline on the 101 mix, is that safe for a stock car without a tune.
Thanks in advance for your replys!

 

You can run the ebc no problem but the race gas will really not do anything without a tune. A mixture of it to get to like 94 oct will help out though. Anything higher I don't think it will produce any significant benefits without a tune.
