Also keen to know what gains you can get from a stock 2007 Liberty GT (Auto). I've had feedback from a couple of tuners to say max of 5% gains without doing the exhaust (DP at a minimum). Basically don't bother with a tune until you replace the dump pipe.
Cheers.
Fueling, timing, WGDC tables and AVCS all affects spool but more importantly, it is torque which makes the biggest difference.
Put it this way, I have a dyno proven 22% power gain on a stock standard as it rolled off the showroom floor condition MY11 STi, which also picked up 30% more torque and yet runs only 0.8psi more boost than stock(15psi, not 14.2psi)
The MY07 Liberty GT 5EAT in even stock form will gain 15% peak power and 18% peak torque on a safe tune
