Added drag configs for the Pessima, Legran, D-series, ETK i-series, Miramar, Covet, and even the T-series.
Added offroad configs for the Barstow, Moonhawk and Covet.
Added a 7.1 liter diesel for the D-series, Barstow, and Moonhawk.
I also edited some of the sound configs for the custom engines. So now the ETK 4.0 V8 sounds like a real V8.
