A set of 240 injectors should be easy to get and pretty cheap as well.
I used to see 30 Mpg in my Starion back in the days of a well ported head and before changing cams, once the car had different cams 26 was average with 28 on long hauls. I have not seen over 30 though but that was all stock parts. I should get a Starion back on the road with the ITB intake I have. I have just not gotten back to that project.

Cheers, Charlie
