Manual M4 G82 back for more💪

Meeting the limitation of the factory clutch we have now gone a upgraded Wagner clutch kit and more push push

A very different platform to tune compared to the automatics and trying to get past the torque limiter was challenging. As we were targeting torque numbers way beyond the factory clutch capabilities from the ramp up of boost. We now have lots of S58 development in the bag👌

This is why we partner and value our relationship with Celtic Tuning, 33 file revisions later, lots of logging and dyno time to get the perfect results🙌

Now making 723 hp and 929Nm on factory fueling and stock turbos on 98Ron

Some wild work from young gun Matt💪

So almost 4 years ago ZADTEC took on a young enthusiast to join the team and soak up all he could🫵

A good mate brought in his Nissan Z wanting a custom exhaust, so the green light was given to young Matt to go rogue😲 and did he deliver👌👌👌🙌🙌

Proud of this one Matt, well done💪
