2G highway mpg

[AZmocoLoco]

working on my GST at the moment, running a 7bolt with an evo3 turbo. airflow is going to be good with a punishment fmic, evo3 intake manifold, FP exhaust, evo3 o2 housing, and 3" piping all the way back. i have an FP 18psi wastegate actuator, tuning it solid at 18psi. i was wondering, what i am looking at for distance at a full tank on highway speeds (65-75mph, using cruise control). going to be running 91 only as well. i dont need a direct answer, im just wondering how much a full tank can take me. also, trying to get off this probationary member junk as well. thanks!

It's pretty relative to how you drive.. with my fwd laser with a 16g and bolt ons I could pull 35mpg or more on the highway. with my GSX with a 68hta and all supporting mods for it I average 24mpg all around and I get about 27-28 on the highway. IIRC the 2gs have better gearing then the 1gs so you might get better then that if you're nice to it.

I wish I could get that mileage. I'm getting anywhere between 14-16mpg depending on how I drive. But, also come to find out the P.O. never got the car tuned.

Averaged about 24 mpg when I had my 97 awd. DSMlink v2, TD05 20g, fmic, BC 272's, ported & polished head, stock block, walbro 255, 680cc injectors.

Probably would have gotten better if I had a better tune! I also noticed I got better gas mileage without using the cruise.

Yeah, it's kind of bad when the toys gets better gas mileage then my regular cars. I have 6, and my 83 Camaro with a 350 (before i blew it up ) got about 22mpg and my GSX now gets that mileage.. everything else is like.. 14-16
