is it an option to find a beater, 20miles isnt much i drive that one way to work and only fill up once a week(full bolt on DE), whens the last tune up, get her on a dyno and find out if its running rich

From your math you get about 50 miles to a tank. Which is less than 5 miles per gallon. Even if your tune was EXTREMELY rich you wouldnt be that low. Look for a fuel leak in the lines somewhere. Or, if you are exaggerating, get the car tuned.

Price you pay when having a turbo car. Stay out of boost.
