Mace memcal upgrade is the easiest improvement in horsepower, torque AND fuel economy on the market. This performance memcal upgrade to your VR V8 Commodore will provide measurable gains in power and torque. Not only that, but your engine will make the power smoother, providing better acceleration and improvement in fuel economy under normal driving conditions!

Each memcal upgrade is recalibrated to suit your specific engine and gearbox type, as well as the model; Ensuring no dodgy soldering or modification to the physical unit, so you can be sure of what you are fitting to your vehicle.

Our performance memcal upgrade features recalibrated fuel and ignition parameters. Hence your engine will be more efficient by burning the fuel and air mixture cleaner, thus making more power. By adjusting these maps within the tune of your Commodore's memcal, we fix the mass-production compromises Holden originally made, unlocking more power across the rev range and providing better fuel economy.

Fuel economy gains will also vary between different models and the condition of your engine. Our conservative estimate is an extra 40 to 50kms (V6) to the tank, but we would expect up to 100kms extra in some models.

 

Key Benefits:

  • Guaranteed power gains, 8kW to 12kW using standard 91-RON fuel. (even more when using 98-RON fuel)
  • Fuel economy improvements.
  • Improved towing capabilities.
  • Easy 10-minute DIY installation.

 

Notes:

  • We arent doing custom memcals.
  • Only an expansion board is supplied in this performance memcal upgrade.
  • This memcal upgrade is for basic bolt on's only. It will not suit after market cams, strokers, turbos, custom superchargers or anything above 10PSI on a L67 Supercharged V6. You will require a custom dyno tune from a reputable workshop.
  • Cam and chip packages can be separately purchased through other listings.
  • Make sure you clean your MAF sensor before installing your memcal upgrade. And cleaning your MAF sensor should be done on a regular basis to keep your cars performance at its best.
  • Our performance memcal upgrades are not suitable for forced induction applications, other than the factory supercharged L67 V6. If you have a highly modified engine or are running a custom supercharged or turbocharged set up, you require a custom one-off tune.
  • Larger horsepower gains are possible when our performance memcal upgrade is used in conjunction with a free-flowing exhaust and a cold-air intake system. These can be purchased through other lisitngs.
  • In case of any confusion, please do not hesitate to contact us.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.) They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo. Just a heads up, they are on the thin side and just a bit see through in the rear. I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.

Extremely comfortable
Color: 02-multicolour (4-pack), Size: X-Large
These are by far the softest and most comfortable underwear I have ever owned. The leg portion absolutely does roll up as so many others have mentioned, however, I did not find that to be uncomfortable at all just annoying that they don’t stay in place. I bought these specific underwear to see if it would help alleviate HS symptoms at all. They have definitely helped with wicking moisture away from the skin. More time will tell if it’s truly helpful for HS. For now, I will recommend these. They are thin, breathable, butter soft, wick moisture comfortable and I would buy again…maybe in a different style next time. I have washed them several times and they seem to be holding up rather well so that is also of supreme importance given the cost of the item. Again, I would recommend this item and plan on purchasing more in a different style very soon.

Eaten by my Thighs
Color: 04-multicolour (4-pack), Size: X-Large
I wanted to love them. Sadly they have let me down. Pros: natural breathable fabric , super soft and comfortable, cotton panty gussets for feminine health and panty liners will stick!! Yay:). And the colors! They are great! But here’s the Con. And it’s the con of all cons. THEY RIDE UP!! Eaten by my thighs. I’m 5’6” and in the general area of 175. I fluctuate depending on how many times I visit the bakery! :) I don’t have a thigh gap but it is not a super tight thigh squeeze. I seldom have thigh climb but these do. I tried two different sizes to see if that made a difference. Nope. I was miserable at a recent theme park in these. I was wearing long heavy dresses and it was quite awkward to yank these legs down non stop. They feel amazing and they have all the requirements 1. Soft 2. Comfortable and stretches with you 3. Breathable with nice thin fabric. Not bulky 4. Natural fibers 5. Great colors If you are a person that is not blessed with Thunder Thighs, please order these. They are great! I wear them at home and to locations that I will not be doing a lot of walking at. I have washed them so many times and they look like new still.
