Custom Tuning

Late Model Holden & HSV V8 Custom Tuning

Our Maf Retained & Mafless Tunes are favorites when it comes to Holden owners with power and better fuel economy in mind. When a Maf-less Tune is performed it requires the removal of the restrictive maf and some airbox ducting mods. The standard airbox can remain but this set up breathes fire when matched to GM Motorsports custom over the radiator filted cold induction setup. Expect awesome throttle response and tyre shredding performance all with perfect street manners.
