A tuned PCM arrived this week from MACE for my VY, car now drives how it should have out of the factory, it is much more a pleasure to drive now, gear shifts now have no delay and from about 2000-5/6000rpm the power output is much more noticeable, normally with say quarter throttle 0-60kph would take a few seconds, now it is already there and I am having to brake as it has been catching me out, power delivery is smooth at light throttle, the car now gets a squat going on once it hits 3000rpm at WOT, I have imported the bin file off my old standard VY and matched it to this one to my laptop and after having a quick 15 minute read of the bin file it looks as though the timing has been advance 5 Degrees across the board as well as a few other tweaks for the transmission shifts, everything else has stayed the same but I am yet to look closer into this so I know what to change on my original for my Supercharged tune when needed, although one thing is I did have extreme popping at 5000+ rpm at first, I am running 98 octane plus +10 octane booster, after I changed the plugs to some new platinum's it was mint so make sure your electrical and spark is optimal
Thanks Steve much appreciated
