I know my combo isn't listed, but just so you know. My setup is in my sig. Heads are milled .030". When I was M6, I got 20.5mpg highway, and about 17-18 mixed. 15mpg while driving hard.

Torquer2 112 +2 cam, with home brew heads @ 11:1 compression.
430 HP, 384 Tq.
25-26 MPG highway @ 75 MPH.
I dont bother calculating city milage, but Its probably really bad. Like single-digits bad. Its all in how you drive it. Around town, I cant help but get on it from every stop

For combo see below for the 99 T/A. Note my set up is pretty old and with a mail order tune.
Typical 21-22 mpg, best highway 28mpg with heads/cam and 4.10 gears
Best before heads and cam. Typical 23.5mpg with a highway best of 32.8mpg.
A friend with a GM Hot Cam, FLP headers and 4.10's was able to get 26 mpg highway. I'm not sure what his normal mpg was but I think it was under 20.

26-27 mpg on highway. The AFR 205 heads and high compression are the key components. My AFR 225 heads and a smaller cam were about 1 mpg worse. Here are my mods:
AFR 205 heads with chamber opened up to 4.00" bore (to better unshroud the valves).
Standard 205cc CNC port work
Revised valve job for better low and mid-lift flow.
Heads milled to achieve 57cc chamber size (static compression 11.92:1)
Comp Cams 238/242 .605/.610 112LSA +3 cam with XE-R lobes
AFR upgrade 8019 dual valve springs. 170 seat, 450 open pressure.
AFR hollow stem 2.02 intake valves that weigh 98 grams each.
Forged shortblock machined by Erik Koenig from HK Enterprises, Houston, TX. Flat top Diamond pistons with 2cc valve reliefs.
7.400" pushords.
Comp R 875 hydraulic roller lifters.
Yella Terra 6645 Ultra Light shaft mounted rockers.
FAST 90 intake velocity ported by Tony Mamo.
Nick Williams 90mm TB.
No MAF (speed density tune by me).
Kooks 1 3/4" headers.
Custom y-pipe with LG Motorsports y-merge 4" collector, no cats.
4" Quick Time electric cutout.
10 bolt with 3.73 gears.
6 speed manual with Textralia OZ700 clutch.
