Hi im the proud new owner of a my03 liberty B4. Mine is automatic. So far i have been really happy with the car, have not noticed any pinging and the valley of death, well i dont think there really is one on mine so i guess im kinda lucky. It goes pretty well, but im lookin at puttin another couple of grand into the perfrormance side of things. Can anyone reccomend what i should do? Im crossed between two lines of thinking, whether to upgrade the air induction plus exhaust, or to upgrade the computer (ecutek 2). Im reading mixed responses about the computer upgrades like one guy sayin he only got 9 kw, then other guys saying they are getting 25-30 kw. Whats the real deal with this ecutek 2 upgrade? I know the s and j website in Adelaide quote an extra 30 kw after the tuning but can these figures be taken seriously. Can anyone who has an auto my03 B4 and has done this upgrade please post me some feedback on what to expect from performance as that would be much appreciated, or even has done the upgrade to any other b4 liberty. Thanks again Peace.
