Whats up guys, I recently bought an 06 sti. It had a 93 tune on it, but since theres not alot of 93 gas stations remotely close to me I tuned it down to the 91 cobb tune. Feels really non boosty now :( Also has a cel on for an o2 sensor that doesnt sound too fun to fix. (should I just buy an oem sensor from subaru?)
