Unforgiven -
It would make sense that the Aura is mostly parted from GM drivetrains, the S-Series was the only "Saturn Unique" drivetrain. Don't know if it will help, but I found this on saturnfans :
Aura on HP Tuners supported vehicles list - SaturnFans Forums

Acording to GM's site:
http://www.gm.com/company/gmability/...ns_051806.html
SPECIFICATIONS: HYDRA-MATIC 6T70 / 6T75
Aura 6T70 / Outlook 6T75
Maximum engine torque:
280 lb-ft (380 Nm) / 301 lb-ft (406 Nm)
Final drive ratio:
2.77 / 3.16:1
Maximum validated gross vehicle weight:
4850 lbs / 6384 lbs
Maximum shift speed:
1-2: 6800 rpm / 1-2: 6800 rpm
2-3: 6800 rpm / 2-3: 6800 rpm
3-4: 6800 rpm / 3-4: 6800 rpm
Final drive ratio:
2.77 / 3.16:1
Fluid type:
DEXRON® VI / DEXRON® VI
I think the Aura could likely gain another 28 lb-ft of torque from 252 stock to 280 with the following upgrades:
Cold Air Intake: 3-4 lb-ft
Cat-Back Exhaust: 8-10 lb-ft
Dyno Tune on 91 Octane: 12-14 lb-ft
Total gain 23-28 lb-ft
Too bad GM didn't put the 6T75 in the Aura but with a 6th gear ratio of 0.63:1 like the Tremec T-56 6-speed manual. It would have given better acceleration the first 5 gears and the same highway mileage in 6th.
