well i allready have a sri and exhaust, and i am planning on doing wires. but i want a turbo, and i plan on taking it to a local shop and having them dyno tune. i am just wondering how much tuning is really necessary. I plan on running low boost, and if i can get it to work, then i will up the boost. I have delt withmany turbo cars, building up of STI's and mazdaspeed miatas, if i wanted speed i would have stayed with those kind of cars. i am just looking to have a fun time in the aveo, and have boost. theres nothing like it.
