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 vehicles factory fitted with the GEN III LS1 5.7L V8, excluding VZ. This allows us to select an appropriate and safe tune to suit your modification, whether it be a cold air intake, full exhaust system, 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 the 220-230rwkw 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:

  • Sharper throttle response.
  • Increased HP and torque.
  • Firmer gear changes.
  • Quicker gear changes.
  • Improved fuel economy.
  • Value for money when compared to a dyno tune.
  • MAF/MAF-LESS tunes available.
  • Change-over ECU options 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 us all the answers.
  • 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.
  • Our preference is that these ECU's are to be sold on a change-over basis due to the limited number we can source.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic. I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop. One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.
