GM Motorsport Performance Tuning - A Must for all late model Holden VT to VE V8's
Our Mafless Tuning is one of our favorite tunes when it comes to Holden V8 owners with power in mind.
You Holden comes out of the factory very de-tuned, when our maf-less tune is performed it requires the removal of the restrictive mass air flow meter and installation of our custom cold air inatake system complete with reusable K&N filter. Expect awesome throttle response and tyre shredding performance all with perfect street manners.
Some of the modification your GM Motorsport tune includes are Speed limiter, RPM limiter, Fuel mixture, Knock retard
& Idle speed adjustments.
