TII gas mileage

Okay, I'm strongly debating the swap into my 86' GXL I've done the research I know what it will take, I know what I'll be doing when I drop it in(I'm thinking S5 motor with BNR stage II) looking to make about 300whp. What I'm asking is what kind of gas mileage are you guys in that range(or any range really) getting. I drive this poor car nearly 80 miles everyday to get to school and work. Naturally these are really easy freeway miles and I've learned to only abuse it on the weekends. Anyway, yeah average MPGs for TII guys this 19mpg out of my NA is bad enough I don't want to take a much harder hit than that.

With a standalone and some tuning you can get good gas mileage. I average 30mpg on the freeway. Hp has nothing to do with gas mileage btw...

True, but running four 720cc injectors can make it a little more difficult(just an example I haven't decided on fuel just yet.)

Hmmmm I'll need to find that injector calculator again but 1680s seems like a WHOLE lot of overkill for 300ish WHP, but I suppose it'd leave plenty of room for when I get greedy.
