D is said to leak slightly from factory, G will eventually break but it holds better boost than G
thats what ive seen plastered all over the MK5 forum anyway.
Maccy,
they are the version letters.. the G being the most recent.
What u mean by working on revo setups?? Cheers
Range 0 Valet Mode

Range 6 Performance Boost
Range 9 Aggressive Boost
Timing Adjustment:
Range 0-3 91(US)/95(Euro) Octane Fuel
Range 4-6 93(US)/98(Euro) Octane Fuel
Range 7-9 Unleaded Race Fuel over 100 Octane
Fuel Adjustment:
Range 0 Stock Air-Fuel Ratio (AFR)
Range 9 Performance Air-Fuel Ratio (AFR)
and AFR of 9 is leaner than 1 (stock) as intuitively you would think it was the other way round. Its not.
