Mace Engineering offers Gen III LS1 custom bench-top reprogramming for your factory ECU using established tuning software. Our high standard for customer service guarantees you'll love the performance gains at prices you won't turn pale at.

Extracting performance and economy from the manufacturer's original engine management computer has become a popular modification in today's modification scene.

We have an extensive range of tunes in our database covering a large variety of modifications, which target all HSV vehicles factory fitted with the GEN III LS1 5.7L V8 engines. This allows us to select an appropriate and safe tune to suit your modification, whether it be a cold air intake, full exhaust system or diff gears etc. Power output will vary based on your vehicle's modifications, but the average LS1 with an intake and an exhaust upgrade will generally make around 220-230 rwkw with a substantial improvement in fuel economy.

In addition to editing the engine calibration, we can also improve the performance of the automatic transmission by accommodating a change in final drive ratio or stall converter, harden up the gear shifts and reduce shift times between gear changes. The choice is yours as we can tailor the tune to suit your needs.

 

Key Benefits:

  • Value for money when compared to a dyno tune.
  • Sharper throttle response.
  • Increased HP and torque.
  • Firmer gear changes.
  • Quicker gear changes.
  • Improved fuel economy.
  • MAF-Less tunes available.

 

Contents:

  • 1 X Performance enhanced engine calibration

Notes:

  • Please fill out our *tune form* and email it back to us following your purchase. There is a "fill and sign" feature under the tools section on adobe to make this process simple and easy. Alternatively, you can just email all the answer back to us.
  • We only do these ECU's on a change-over basis due to the limited number we can source, so the customer must send their PCM first with a completed tune form.
  • Our remote tunes can only currently cater for minor bolt-on modifications. Upgrades such as larger injectors, camshaft, modified heads and forced induction will require a dyno tune.

They keep sheets from getting greasy.
Size: 3 Pairs - Gray
These are good. I like that I can put lotion on my heels when I go to bed and not get my sheets greasy. They do a good job on that and a pretty good job keeping the moisturizer on. Since the toes are open, they aren’t hot. The gel doesn’t seem to do anything, though.

These socks are so cool and I have used them every night for a week and can see a difference. I am using them with the gold bond heel lotion.

love these for soft feet!!
Size: 3 Pairs - Gray, Green, Pink
these are great. My feet are soft already! What I like best is my feet. Don't get hot in them because the heels and toes are exposed.
