Hi Jim, I was also keen on a tune from Gazoo. A chief engineer here in Australia recently went to training session and aked the question for me. The reponse is that Toyota / Gazoo/ TRD ... have no intention of bring out an aftermarket tuning package and are leaving it to the aftermarket suppliers only. SAD I was hoping for more support from Toyota!I'll be waiting for the Japanese to come out with a tune. Warranty won't be voided if it's from TRD or Gazoo. I'd like to see HKS come up with a tune too. I like to bet my money and peace of mind on the Japanese.
