You do not put a jet "chip" in your car. you send jet your ECU and they "do something" to it. There has been lots of talk on hear and the supra forums that JET does nothing but put a sticker on the ecu and call it a day.

I am curious if anyone has a before and after dyno.

I hear that you cannot hack a Toyota ecu so I dunno how jet does it.............
