Any advice on who and where to get this done? Who has done this and was it worth it?
Dastek?
Me Me Me Me.
Done it with Unichip.
No gain, so money down the drain.
I did it purely to try and reolve my ping issue. It's like our No1, you can do what you want, it just won't go away.
They "did correct the AF ratio calibration" or something like that, but in all honesty, i still think there's a hole in the tank.

It did prove that my ping issue is
NOT timing related, because i still get ping even at -10' timing.
I now firmly believe it is compression related. The only thing that seems to take ping away on my car is Octane Boost.
Octane boost is expensive, so I drive at <2000 rpm or > 3000 rpm. This means on highway about 130-140km/hr, so fuel consumption is in it's moer.
