I put the turbo on my diesel I instantly got 2 to 2.5 MPG increase. Then adding the second turbo and intercooler got me maybe another 0.5mpg.
Turbos just don't really increase the fuel economy of gas engines. On a gas engine the turbo and throttle fight each other constantly, any gains are lost there.
