Can Mace recommend someone to custom tune my vehicleand is there some kind of warrenty on it? Also what power gain do you think I'll be able to grasp with how the car sits currently cause I have heard I can't put headers or cats on this model without a tu

Jon from

http://www.jwracing.com.au/  can certainly help. Just let him know that Steve from MACE put you onto him and you'll be looked after.The tune its self comes with a lifetime warranty. This would be independent of the rest of the vehicle, which is out of our domain.His post covers the info you're after, if you have an LLT V6. It would definitely fix the same.We certainly have a few workshops in Brisbane who could help you out, however I would recommend JW Racing as the first point of call.
