Yea they are,
I think, Mick @ Tech workz will do any jobs better than anyone in ACT region, hope you might have heard of them, also DTS Fyshwick.
Have you got Ecu-TEK done on your Liberty by Ultimate? Hows it? Are you happy?
I have had Ecu-TEK (MRT XB kit) done on my 02 Rexy STi while I was residing in Sydney, I thought they were the best people, LOL
mainly because they lock us into EcuTEK and we cannot go to any other tuner except for an authorised MRT one. Secondly, they will scare us with lies and make us believe their software is our salvation and anything else will blow up your engine. Bull Shit!!!!
Pulse Racing is really great, especially their service and won't give us heart attack at the end of the day (from my experience and also heard from others).
What are the mods you got at present on you Liberty?
Cheers
