What if I told you that you can have a highway missle AND still get 30mpg? 6k into a turbo for the teggy will net you more power than you can use. You didn't mention if your teggy manual or auto, doesn't matter since both will run the stink off any quarter mile. Gear it right and it'll be a rocket up to 85mph, and then coast at low rpm for mileage. You could even switch between tunes on the fly.
