Dealer through Toyota for a TRD centrifigul supercharger is $3200 and $800 for install but it also falls under your 5 year 60k warranty.If you buy from TRD I believe there is only a 12 month 12k warranty.Chance’s are if you buy it and install it yourself you are going to muck up the tune or something.The TRD Flash device hooks up directly to Toyota’s System and they download the tune from there.
If you get a TRD blower and an aftermarket tune and something goes wrong than TRD and Toyota can blame the tuning company for the issue that is present.Toyota is not just selling the supercharger but they are selling it with the powertrain warranty.
