JET is a fairly well known ECU "reprogrammer". Many have questioned what they acutally do...this page has some photos of the take apart of an '87 Toyota Supra Turbo ECU that had been "tuned" by JET.

If you know anything about the MKIII's ECU, you know that the ROM Is on the processor and its non-flashable. This means that you can't just reprogram it, you must remove the current processor, add a daughterboard w/separate ROM and processor. Clearly, all JET does is place a sticker in your ECU and seal the ECU closed so you will think they actually did something. Does this sticker add the claimed HP/TQ? That's for you to decide....
