    Wondering where I can get my VE Series 1 Omega tuned (4spd Auto). It has 12mm manifold insulators, quad tip dual exhaust, and an Orssom OTR intake.
    I have a USB-OBD cable so remote tune is also an option.
    Heard MACE has stopped tuning the Alloyecs?

    from the chiptorqe website


    Our dyno experience has shown that the standard Holden tune is accurate for a standard vehicle, even a vehicle with an upgraded exhaust and/or cold air intake. This is due to the sophistication of the engine management system self learning for different air flow characteristics and even fuel qualities.

    ChipTorque recommend upgrades like the CPR6 manifold or supercharger kits before a tuning solution can benefit the car. Additionally the tuning software we use for the factory ECU only supports to 09/2007 models. ChipTorque alternatively offer the XEDE Processor as a tuning option for the late model Alloytec, but this will still need the suggested level of modifications.

    So basically at your point, not really worth it.

    It's just that after installing the exhaust it seems to be using way more fuel, as in ~4L/100km more... Even replaced the spark plugs and coils.

    if you have a scan tool I would be looking at your O2 data and fuel trims. An exhaust should effect that. Is it maybe your style of driving IE. new exhaust (louder) that maybe your putting your foot into it more?

    Even freeway/highway driving has gone up though, just steadily sitting at around 100km/hr. I have a scan tool I keep in the car so I could check that.

    I have read people who have put those manifold insulators on have experienced higher fuel use.

    prolly o2 sensors. Could have damaged them when swapping the exhaust happens alot, its most likely the culprit.

    I thought manifold insulators were meant to improve fuel consumption? :(
    Don't think it'd be the O2 sensors since I put brand new ones in when I put in the new exhaust. I was thinking it would be because of the extra pipe with the new exhaust?

    I've found that my consumption is lower with them , it depends on your driving style

    hook your tool up check your 02 sensors. An exhaust is not going to change fuel economy to drastically at all, it could only be a few things who knows maybe your new o2 sensor is faulty, you could have the incorrect ones for your model as I looked into this myself when swapping exhaust depending on your year could be a few different part numbers for 02 sensors. Anyway a check on the ecu should show up a simple o2 problem. Once I fitted my dual exhaust on my v6 going from a single I noticed improved fuel economy extra 50klms every single tank consistantly.

    I'll check my O2 sensors :(
    Could it be incorrect spacing on my spark plugs or something? I set the space slightly shorter than the ones I pulled out.
    Also, I got quoted $600 for a remote tune from OzTrack. Didn't MACE used to do it for like $400 or something?

    Mybe it is your spark plu gap. I would have though though a smaller gap would produce a better spark and therefore better more efficient combustion.

    It'll be hotter but not better imagine you need to start a fire asap, would you use a lighter that burns at 1000 degrees or a flamethrower that is only500 degrees, it's a trade of of surface area/ to heat.
