I get just under 31mpg with Cobb stage 2 mods and Dizzy stage 2 tune. I used to get 33 when it was stock. Like you said, using cruise control is a big help. I also get to 6th gear very quickly on the streets, though without being a slowpoke.
It’s easier now with that great torque bump from the mods. First gear pulls more like it should, so I can build momentum and keep the revs low in all gears and not drive at granny speeds.
