I know 91 is the gas to put in for the 06 STi, but I was wondering what brand do most of you guys use? I hear all different stories about how 76 is better then Chevron and visa versa. Any opinions?

Was also wondering what do you think a good exhaust system is to put on an 06 STi, how wide should the piping be? down pipes? straight pipes? What are the options to go with?

When does the turbo usually kick in? Like what RPM?

Last question is about the ECU Reflash. People have been saying go with Vishnu, others say Vishnu sucks... Lemme know your opinions on where to go for a reflash.


Thanks Guys and Girls if any =P

 

Well perfsonally i use 76, no real data to say its better just my personal preference. as far as exhaust go a Helix 3" down pipe and any catback will be fine. I do not like vishnu due to the fact that they tune way to aggressive and have blown quite a few motors. A cobb accessport works great and you can get it protuned here in the bay area at www.finelineimports.net. Brett
