A question for Cayenne TT owners, any of you tried or are running Giac or Revo software? What are your thoughts on its performance difference? And any other software that you would consider for the Cayenne Turbo? I am mainly interested on either Giac or Revo because they are readily available in Australia and are lot cheaper than DMS or Gemballa, at least in Australia they are.

Thanks in advance.

I'm sure they are all quite similar in terms of performance increase. In my experience, I used Sportec at first who came to the MAHA dyno, then had a custom program made by AMS after the results were not what we wanted. I based my decision on the results from the MAHA dyno. In my case, there were some other factors such as cracked coil packs that may have negatively altered Sportec's results on the dyno.

GIAC is very popular in my region for the same reasons you state - price. But I didn't have the time to go back and forth between a GIAC dealer and then the dyno shop, etc. Sportec is a great company that backs their product.

If you reseller in Australia can unconditionally guarantee the claimed hp/torque increases on the dyno, then you should go with the company that'll back up their product !
