You're definitely right about the turbo. I have an Audi 1.8T and all the hypermiling I've tried only helps .7-.8 MPG. But when the turbo was broken I easily got another 3 MPG! Pretty much any acceleration over idle starts to dig into the turbo, maybe rechipping it would help but usually those mods are for more HP not less.
