The mafless tune is customized to suit the engine and its modifications, i.e. the 6.0L VZ L76 or the VE L98, LS3 and LS7.

Our tunes are well known worldwide since we are using EFILive in a very innovative way to provide mafless tunes that have stable Air Fuel Ratios at all loads.

The Mafless tune is required to make full use of other modifications including over radiator style air intakes. We can also tune using the maf (its just not as smooth in power delivery as the mafless tune)
The A6 gearbox is an extra $150. This gives the box improved shift quality and improves its feel with shiftpoints etc.
