SV6, Piggyback or Tune?

[CKaras]

Hey guys, just thought I'd start a topic as I don't really know what is of more benefit for the Auto SV6.
I know a group called Powerchip have a flash tune for the SV6 for $900, they claim that it achieves a gain of 10-11KW on 98 Premium Unleaded. I was just wondering if anyone else has had this installed or what other path have they chosen and has it been beneficial? There is of course the Dyno option but as I'm new to the modifying scene I would like to know the best tuning method for the SV6 in terms of power and economy.

thw powerchip tune is really a generic tune...

the vcm suite custom tune is really the best option, it tunes your car with all your modifications, and its heaps cheap to get tune touched up with further mods rather than a full tune...

vcm suite tunes net better results too
