We have developed a VCM suite tune for the Alloytec, just flash it in and go, no piggyback mods from us. No piggybacks for us, NO SIR
Not sure what kind of quartermile you think you want, maybe post that up as obviously there is something you would be happy with just reading between the lines. We have Brisbane customer with VS Comm 8.8psi on 13.3 quartermile for Ecotec which is not too shabby for a basic setup with a cooler added in later and no matching tune.
The $20k bit is interesting, our agent in brisbane is doing VZ Alloytec drive in drive out $5500. Can't see why a VE could be anything much more.
